Java - Float equals() method



Description

The Java Float equals() method compares this object against the specified object. The result is true if and only if the argument is not null and is a Float object that represents a float that has the same value as the float represented by this object.

Declaration

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

public boolean equals(Object obj)

Parameters

obj − This is the object to compare with.

Return Value

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

Exception

NA

Example 1

The following example shows the usage of Float equals() method to check equality of two float objects. We've initialized two Float objects with same underlying value. Then using equals() method, we're checking the equality.

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {

      // compares this object against the specified object
      Float obj1 = new Float("2");
      Float obj2 = new Float("2.0");
      System.out.print(obj1 + " = " + obj2);
      System.out.println(" ?  " + obj1.equals(obj2)); 
   }
} 

Output

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

2.0 = 2.0 ?  true

Example 2

The following example shows the usage of Float equals() method to check equality of two float objects. We've initialized two Float objects with different underlying values. Then using equals() method, we're checking the equality.

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {

      // compares this object against the specified object
      Float obj1 = new Float("3.0");
      Float obj2 = new Float("5.0");
      System.out.print(obj1 + " = " + obj2);
      System.out.println(" ?  " + obj1.equals(obj2)); 
   }
} 

Output

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

3.0 = 5.0 ?  false

Example 3

The following example shows the usage of Float equals() method to check equality of two float objects. We've initialized one Float object with a value and keeping other Float object as null. Then using equals() method, we're checking the equality.

package com.tutorialspoint;
public class FloatDemo {
   public static void main(String[] args) {

      // compares this object against the specified object
      Float obj1 = new Float("3.0");
      Float obj2 = null;
      System.out.print(obj1 + " = " + obj2);
      System.out.println(" ?  " + obj1.equals(obj2)); 
   }
} 

Output

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

3.0 = null ?  false
