자바 메소드 호출과 리턴값(java call a method and return)

이런식으로 리턴값을 선언할 수도 있다.

package study;

public class CalculatorExample {

public static void main(String[] args) {

double result1 = 10 * 10 * Calculator2.pi;

int result2 = Calculator2.plus(10, 5);

int result3 = Calculator2.minus(10, 5);

System.out.println("result1 : " + result1);

System.out.println("result2 : " + result2);

System.out.println("result3 : " + result3);

}

}

class Calculator2 {

static double pi = 3.14159; 

static int plus(int x, int y)

{

return x + y;

}

static int minus(int x, int y)

{

return x - y;

}

}
