Java Double toString() Method

Java toString() method is a part of the Double class of the java.lang package. This method returns the String object with its value equivalent to the Double Object.

In short, this method is used to convert Double Object into String.

Syntax:

public String toString()  

Parameters:

No parameters are passed in this method.

Returns:

Returns the String representation of the Double Object.

Example 1:

Here, the Double objects are converted into its equivalent String representations.

import java.lang.Double;
public class StudyTonight
{  
    public static void main(String[] args) 
      {  
        Double a = 50.67;       
        String s1 = a.toString();  // return a string value 
        System.out.println("Equivalent String is " + s1);              
        
        Double b = -18.80;            
        String s2 = b.toString();  // return a string value 
        System.out.println("Equivalent String is " + s2);  
      }  
}  

Equivalent String is 50.67
Equivalent String is -18.8

Example 2:

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

import java.util.Scanner;  
public class StudyTonight
{  
     public static void main(String[] args) 
       {  
          try
           {
             System.out.print("Enter the value ");  
             Scanner sc = new Scanner(System.in);  
             Double val = sc.nextDouble();  
             String s = val.toString(); //converting to string
             System.out.println("String value is : "+ s);  
         
           }
         catch(Exception e)
           {
           System.out.println("Invalid input!!");
           }     
        }  
}  

Enter the value 89.55
String value is : 89.55
***************************
Enter the value -44.89
String value is : -44.89
***************************
Enter the value 0x556
Invalid input!!
