Java comparison using the compareTo () method


public static void main(String[] args) {
        System.out.println("-----a.compareTo(b)Let's use!-----");
		//When a is large
		Integer a = 2;
		Integer b = 1;
		System.out.println("If a is larger" + " " +a.compareTo(b)); //1 returns
       //When a is small
		a = 1;
		b = 2;
		System.out.println("If a is smaller" + " " +a.compareTo(b)); // -1 returns
      //If a and b are the same number
		a = 1;
		b = 1;
		System.out.println("When a and b are the same" + " " +a.compareTo(b)); //0 is returned

compareTo () ・ ・ ・ ・ I still don't know how to use it (laughs)
