Java - Boolean Class equals() Method

Boolean class equals() method: Here, we are going to learn about the equals() method of Boolean class with its syntax and example. By Preeti Jain Last updated : March 17, 2024

Boolean 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.


public boolean equals(Object ob);


  • Object ob – represents the Object to compare with.

Return Value

The return type of this method is boolean - it returns a boolean value based on the following cases,

  • It returns true, if Object1 is equal to Object2.
  • It returns false, if Object1 is not equal to Object2.


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

public class EqualsOfBooleanClass {
    public static void main(String[] args) {
        boolean b1 = true;
        boolean b2 = true;

        // Boolean Object initialization
        Boolean ob1 = new Boolean(b1);
        Boolean ob2 = new Boolean(b2);

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

        // It compare two objects of Boolean 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");
            System.out.println("Both objects are not equal");


ob1: true
ob2: true
ob1.equals(ob2): true
Both objects are equal
