Obs.: don't forget the endline after all.

Resolução:

 

import java.util.Scanner;

public class Main {

 

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

int a, b, x;

a = sc.nextInt();

b = sc.nextInt();

Area of a Circle

Adapted by Neilor Tonin, URI  Brazil

Timelimit: 1

 

The formula to calculate the area of a circumference is defined as A = π . R2. Considering to this problem that π = 3.14159:

Calculate the area using the formula given in the problem description.

Input

The input contains a value of floating point (double precision), that is the variable R.

Output

Present the message "A=" followed by the value of the variable, as in the example bellow, with four places after the decimal point. Use all double precision variables. Like all the problems, don't forget to print the end of line after the result, otherwise you will receive "Presentation Error".

 

Resolução:

 

import java.util.Scanner;

import java.util.Locale;

public class Main {

 

public static void main(String[] args) {

Locale.setDefault(Locale.US);

Scanner sc = new Scanner(System.in);

double r, pi = 3.14159, a;

r = sc.nextDouble();

a = Math.pow(r, 2) * pi;

System.out.printf("A=%.4f\n", a);

      }

}

No caso desse programa, eu utilizei o Scanner, que te dá liberdade para digitar no console para a maquina ler, de acordo com a variável!

E usei também o Locale, a qual te permite habilitar as regras gramaticais de cada pais, eu sempre utilizo o US(United States) no locale,  para que eu possa digitar números reais sem utilizar virgulas para separar os números.

Com idioma BR, você utiliza "virgula" para separar os números, exemplo: 2,0... quando você digitar no console.

Com idioma US, você utiliza "ponto" para separar os números, exemplo: 2.0... quando você digitar no console.

Também utilizei o Math.pow(a , n) , ele te permite a potencializar a base(a) por tantas vezes o expoente(n),  para resumir, supomos que o numero 2 seja representado pela letra A, e seu expoente seja 4, então em vez de você criar uma linha de: A * A * A * A, apenas precisaria do Math.pow(A , 4);.

E na hora da maquina escrever para você, utilizei o System.out.printf, esse modo de leitura te permite formatar tudo que está dentro dele de acordo com a variável: 

String palavra = %s;

Int inteiro = %d;

double / float real = %.(algum numero).f;  A quantidade de números dentro do "algum numero", ler para você a quantidade de números após a parte inteira, ou seja, depois da virgula. 

Exemplo: parte inteira , decimo centésimos milésimos.  = 4.123

Se você colocar %.0f, ele entrega apenas o valor inteiro;

Char letra = %c;

Para pular a linha, você pode usar %n ou \n;

%n = pula linha com espaço após a leitura.

\n = não deixa espaço após a leitura.

e para ler tudo, basta apenas fazer tudo Concatenado entre aspas, seguido do nome dado a cada variável, exemplo:

System.out.printf("%s, %d, %.4f, %c%n", palavra, inteiro, real, letra) ;

 

E sobre boas práticas sempre informe os números de acordo com a variável:

Caso tenha que multiplicar uma variável doublé por um numero, e supondo que essa variável seja A, bote A * 2.0, utilize do 0 após a virgula para o numero double ser reconhecido.

 

e se for float, utilize de A * 2f, para que o numero float seja reconhecido.

Time Conversion

Adapted by Neilor Tonin, URI  Brazil

Timelimit: 1

Read an integer value, which is the duration in seconds of a certain event in a factory, and inform it expressed in hours:minutes:seconds.

Input

The input file contains an integer N.

Output

Print the read time in the input file (seconds) converted in hours:minutes:seconds like the following example.

 

Resolução:

 

 

import java.util.Scanner;

import java.util.Locale;

public class Main {

 

public static void main(String[] args) {

Locale.setDefault(Locale.US);

Scanner sc = new Scanner(System.in);

int tempo, horas, resto, minutos, segundos;

tempo = sc.nextInt();

horas = tempo / 3600;

resto = tempo % 3600;

minutos = resto / 60;

segundos = resto % 60;

System.out.printf("%d:%d:%d\n", horas, minutos, segundos);

sc.close();

 

}

 

}

 

OBS: O OPERADOR MOD( % ) É O RESTO DA DIVISÃO DO DIVIDENDO / DIVISOR, a regra se aplica apenas para os calculos.

Age in Days

Adapted by Neilor Tonin, URI  Brazil

Timelimit: 1

Read an integer value corresponding to a person's age (in days) and print it in years, months and days, followed by its respective message “ano(s)”, “mes(es)”, “dia(s)”.

Note: only to facilitate the calculation, consider the whole year with 365 days and 30 days every month. In the cases of test there will never be a situation that allows 12 months and some days, like 360, 363 or 364. This is just an exercise for the purpose of testing simple mathematical reasoning.

Input

The input file contains 1 integer value.

Output

Print the output, like the following example.

 

Resolução: 

 

 

import java.util.Scanner;

import java.util.Locale;

public class Main {

 

public static void main(String[] args) {

Locale.setDefault(Locale.US);

Scanner sc = new Scanner(System.in);

int dias, anos, meses, dia, resto;

dias = sc.nextInt();

anos = dias / 365;

resto = dias % 365;

meses = resto / 30;

dia = resto % 30;

System.out.println(anos + " ano(s)");

System.out.println(meses + " mes(es)");

System.out.println(dia + " dia(s)");

sc.close();

 

}

Selection Test 1

Adapted by Neilor Tonin, URI  Brazil

Timelimit: 1

Read 4 integer values A, B, C and D. Then if B is greater than C and D is greater than A and if the sum of C and D is greater than the sum of A and B and if C and D were positives values and if A is even, write the message “Valores aceitos” (Accepted values). Otherwise, write the message “Valores nao aceitos” (Values not accepted).

Input

Four integer numbers A, B, C and D.

Output

Show the corresponding message after the validation of the values.

 

Resolução:

 

 

import java.util.Scanner;

import java.util.Locale;

public class Main {

 

public static void main(String[] args) {

Locale.setDefault(Locale.US);

Scanner sc = new Scanner(System.in);

int a, b, c, d;

a = sc.nextInt();

b = sc.nextInt();

c = sc.nextInt();

d = sc.nextInt();

if(b > c && d > a && c + d > a + b && c > 0 && d > 0 && a % 2 == 0) {

System.out.println("Valores aceitos");

}

else {

System.out.println("Valores nao aceitos");

}

sc.close();

 

}

 

}

Banknotes and Coins

By Neilor Tonin, URI  Brazil

Timelimit: 1

Read a value of floating point with two decimal places. This represents a monetary value. After this, calculate the smallest possible number of notes and coins on which the value can be decomposed. The considered notes are of 100, 50, 20, 10, 5, 2. The possible coins are of 1, 0.50, 0.25, 0.10, 0.05 and 0.01. Print the message “NOTAS:” followed by the list of notes and the message “MOEDAS:” followed by the list of coins.

Input

The input file contains a value of floating point N (0 ≤ N ≤ 1000000.00).

Output

Print the minimum quantity of banknotes and coins necessary to change the initial value, as the given example.

 

Resolução:

 

 

import java.util.Scanner;

import java.util.Locale;

public class Main {

 

public static void main(String[] args) {

Locale.setDefault(Locale.US);

Scanner sc = new Scanner(System.in);

int notas, moeda, moedas, resto, nota;

double valor;

valor = sc.nextDouble();

resto = (int) (valor * 100);

System.out.println("NOTAS:");

nota = 100;

notas = resto / (nota * 100);

System.out.printf(notas + " nota(s) de R$ %d.00\n", nota);

resto %= (nota * 100);

nota = 50;

notas = resto / (nota * 100);

System.out.printf(notas + " nota(s) de R$ %d.00\n", nota);

resto %= (nota * 100);

nota = 20;

notas = resto / (nota * 100);

System.out.printf(notas + " nota(s) de R$ %d.00\n", nota);

resto %= (nota * 100);

nota = 10;

notas = resto / (nota * 100);

System.out.printf(notas + " nota(s) de R$ %d.00\n", nota);

resto %= (nota * 100);

nota = 5;

notas = resto / (nota * 100);

System.out.printf(notas + " nota(s) de R$ %d.00\n", nota);

resto %= (nota * 100);

nota = 2;

notas = resto / (nota * 100);

System.out.printf(notas + " nota(s) de R$ %d.00\n", nota);

resto %= (nota * 100);

System.out.println("MOEDAS:");

moeda = 100;

moedas = resto / moeda;

System.out.println(moedas + " moeda(s) de R$ 1.00");

resto %= moeda;

moeda = 50;

moedas = resto / moeda;

System.out.println(moedas + " moeda(s) de R$ 0.50");

resto %= moeda;

moeda = 25;

moedas = resto / moeda;

System.out.println(moedas + " moeda(s) de R$ 0.25");

resto %= moeda;

moeda = 10;

moedas = resto / moeda;

System.out.println(moedas + " moeda(s) de R$ 0.10");

resto %= moeda;

moeda = 5;

moedas = resto / moeda;

System.out.println(moedas + " moeda(s) de R$ 0.05");

resto %= moeda;

System.out.println(resto + " moeda(s) de R$ 0.01");

sc.close();

}

}
