Java Integer compareTo() Method
Example
Compare Integer objects:
public class Main {
public static void main(String[] args) {
Integer a = 5;
Integer b = 10;
System.out.println(a.compareTo(b));
System.out.println(b.compareTo(a));
System.out.println(a.compareTo(5));
}
}Definition and Usage
The compareTo() method compares the value of an Integer object with the value of another Integer.
It returns 0 if the values are equal, a number less than 0 if this Integer is smaller, and a number greater than 0 if this Integer is larger. Java uses this method when it sorts a list of numbers.
Tip: To compare two int values, use the static compare() method.
