Java - Long Class equals() Method

Long class equals() method: Here, we are going to learn about the equals() method of Long class with its syntax and example. By Preeti Jain Last updated : March 20, 2024

Long class equals() method

• equals() method is available in java.lang package.
• equals() method is used to check equality or inequality of this Object against the given Object or in other words we can say this method is used to compare two objects.
• equals() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• equals() method does not throw an exception at the time of comparing two Objects.

Syntax

public boolean equals(Object ob);

Parameters

• Object ob – represents the Object to compare with.

Return Value

The return type of this method is boolean, it returns true if Object1 is equal to Object2, else it returns false.

Example

// Java program to demonstrate the example 
// of boolean equals(Object o) method of Long class

public class EqualsOfLongClass {
    public static void main(String[] args) {

        // Long Object initialization
        Long ob1 = new Long(10);
        Long ob2 = new Long(20);

        // Display ob1,ob2 values
        System.out.println("ob1: " + ob1);
        System.out.println("ob2: " + ob2);

        // It compare two objects of Long type
        // by calling ob1.equals(ob2)
        boolean compare = ob1.equals(ob2);

        // Display result values
        System.out.println("ob1.equals(ob2): " + compare);

        if (compare == true)
            System.out.println("Both objects are equal");
        else
            System.out.println("Both objects are not equal");
    }
}

Output

ob1: 10
ob2: 20
ob1.equals(ob2): false
Both objects are not equal
