JAVA 객체화 - 인스턴스

class Calculator{
	int left, right;
	
	public void setOprands(int left, int right) {
		this.left = left;
		this.right = right;
	}
	public void sum() {
		System.out.println(this.left + this.right);
	}
	public void avg() {
		System.out.println((this.left + this.right)/2);
	}
}



public class 객체 {
	
public static void main(String[] args) {
	Calculator c1 = new Calculator();
	c1.setOprands(10, 20);
	c1.sum();
	c1.avg();
	
	
	Calculator c2 = new Calculator();
