Java - Long equals() method

---

---

Description

The Java Long equals() method compares this object to the specified object. The result is true if and only if the argument is not null and is an Long object that contains the same long value as this object.

Declaration

Following is the declaration for java.lang.Long.equals() method

public boolean equals(Object obj)

Parameters

obj − This is the object to compare with.

Return Value

This method true if the objects are the same, else false.

Exception

NA

Example 1

The following example shows the usage of Long equals() method to compare two Long objects. We've created two Long objects with different long values. Then using equals() method, we're checking and printing the result of objects being equal or not.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj1 = new Long(32L);
      Long obj2 = new Long(75L);
      System.out.print("Is obj1 and obj2 equal ? ");
      System.out.println(obj1.equals(obj2));
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Is obj1 and obj2 equal ? false

Example 2

The following example shows the usage of Long equals() method to compare two Long objects. We've created two Long objects with same long value. Then using equals() method, we're checking and printing the result of objects being equal or not.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj1 = new Long(32L);
      Long obj2 = new Long(32L);
      System.out.print("Is obj1 and obj2 equal ? ");
      System.out.println(obj1.equals(obj2));
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Is obj1 and obj2 equal ? true

Example 3

The following example shows the usage of Long equals() method to compare two Long objects. We've created two Long objects with same string of long value . Then using equals() method, we're checking and printing the result of objects being equal or not.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj1 = new Long("32");
      Long obj2 = new Long("32");
      System.out.print("Is obj1 and obj2 equal ? ");
      System.out.println(obj1.equals(obj2));
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Is obj1 and obj2 equal ? true

Example 4

The following example shows the usage of Long equals() method to compare two Long objects. We've created two Long objects with different string of long value. Then using equals() method, we're checking and printing the result of objects being equal or not.

package com.tutorialspoint;
public class LongDemo {
   public static void main(String[] args) {
      Long obj1 = new Long("32");
      Long obj2 = new Long("75");
      System.out.print("Is obj1 and obj2 equal ? ");
      System.out.println(obj1.equals(obj2));
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Is obj1 and obj2 equal ? false
