Java – double to string conversion

There are following two ways to convert double to String:

Method 1: Using valueOf() method

public static String valueOf(double d): We can convert the double primitive to String by calling valueOf() method of String class. This method returns the string representation of the double argument.

double var = 22.22;
String str = String.valueOf(var);

Method 2: Using toString() method

public String toString( ): This is the another method that can be used to convert double to String. This method returns a string representation of the Double object. The primitive double value represented by this object is converted to a string.

double var = 33.33;
String str = Double.toString(var);

Complete code

package com.beginnersbook.string;

public class DoubleToString {
   public static void main(String[] args) {
        
       /* Method 1: using valueOf() method
        * of String class
        */
       double dvar = 101.11;
       String str = String.valueOf(dvar);
       System.out.println("String is: "+str);
        
       /* Method 2: using toString() method 
        * of Double class
        */
       double dvar2 = 200.202;
       String str2 = Double.toString(dvar2);
       System.out.println("String2 is: "+str2);
   }
}

Output:

String is: 101.11
String2 is: 200.202
