The difference between multiple ifs and multiple else ifs in Java

1. Multiple ifs are executed regardless of whether you are in front of ture or not  
2. else if if one of the former is true, then none of the latter are executed

public class Test {
	public static void main(String[] args) {
		int a = 1;
		if (a == 1) {
			System.out.println("1");
		}
		if (a == 2) {
			System.out.println("2");
		}
		if (a == 3) {
			System.out.println("3");
		}
		if (a == 1) {
			System.out.println("1");
		} else if (a == 2) {
			System.out.println("2");
		} else if (a == 3) {
			System.out.println("3");
		} else if (a == 4) {
			System.out.println("4");
		}
	}

}
