代码实例：

import java.util.Scanner;

public class Main {
	public static void main(String args[]) {
		Scanner scanner = new Scanner(System.in);
		int a = scanner.nextInt();
		int b = scanner.nextInt();
		int c = scanner.nextInt();
		int d = scanner.nextInt();
		
		int e = c-a;
		int f = d-b;
		if(f<0) {
			e = c-a-1;
			f = d-b+60;
		}
		System.out.println(e+" "+f);
		scanner.close();

	}
}

注意，我们要考虑d-b<0的时候
