Java Number Class

The equals() method is used to determine whether a Number object is equal to the method's parameter.

Syntax

public boolean equals(Object o)

Parameters

o -- Any object.

Return Value

If the Number object is not null, and its type and numerical value are both equal to the method's parameter, it returns True; otherwise, it returns False.

Double and Float objects have some additional conditions. You can refer to the API manual: JDK 1.6.

Example

public class Test{
    public static void main(String args[]){
        Integer x = 5;
        Integer y = 10;
        Integer z = 5;
        Short a = 5;
        System.out.println(x.equals(y));
        System.out.println(x.equals(z));
        System.out.println(x.equals(a));
    }
}

Compile the above program, the output result is:
