[자바 (Java)] 2-2. 변수의 캐스팅

package ex01;

public class Var02 {
    public static void main(String[] args) {
        // 1. 묵시적 형변환 (암묵적) - 업캐스팅
        int n1 = 10;
        double n2 = 10.5;

        n2 = n1;

        System.out.println(n2);

        // 2. 명시적 형변환 (강제로) - 다운캐스팅
        int n3 = 5;
        double n4 = 5.5;

        n3 = (int) n4;

        System.out.println(n3);
    }
}

1. 묵시적 형변환

package ex01;

public class Var02 {
    public static void main(String[] args) {
        int n1 = 10;
        double n2 = 10.5;

        n2 = n1;

        System.out.println(n2);
    }
}

2. 명시적 형변환

package ex01;

public class Var02 {
    public static void main(String[] args) {
        int n3 = 5;
        double n4 = 5.5;

        n3 = (int) n4;

        System.out.println(n3);
    }
}
