Java Float longValue() Method

Java longValue() method belongs to the Float class of the java.lang package and is inherited from the Number class. This method returns the long equivalent of the Float object after a primitive narrowing conversion(Conversion of a higher type to lower type).

In short, this method is used to convert a Float object into a long value.

Syntax:

public long longValue()  

Parameter:

No parameter is passed in this method.

Returns:

The long equivalent of the Float object that is created after conversion.

Example 1:

Here, using the longValue() method, the Float object is converted into its long equivalent.

import java.lang.Float;

public class StudyTonight
{  
    public static void main(String[] args) 
      {  
        //converting Float object into long
          Float x = 15.90f;
          long i=x.longValue();
          System.out.println("Long value is " +i);
          
          Float y = 67.41f;  
          long d = y.longValue();  
          System.out.println("Long value is " +d);
      }  
}

Long value is 15
Long value is 67

Example 2:

Here is a user-defined example where anyone using this code can put a value of his choice and get the equivalent long value.

import java.util.Scanner;  
public class StudyTonight
{  
    public static void main(String[] args) 
    {  
         try
           {
              System.out.print("Enter the value to be converted : ");  
              Scanner sc = new Scanner(System.in);  
              float i = sc.nextFloat();  
              Float n = i ;  
              long val = n.longValue();  //converting Float object into long
              System.out.println("Long Value is: " + val);  
           }
         catch(Exception e)
           {
              System.out.println("not a valid float"); 
           }
    }
}

Enter the value to be converted : 94.90
Long Value is: 94
*******************************************
Enter the value to be converted : 0X900.9
not a valid float
