How to Convert a Double value to String value in Java with Examples
Last Updated :

Given a Double value in Java, the task is to convert this double value to string type.
Examples:
Input: 1.0
Output: "1.0"
Input: 3.14
Output: "3.14"
Approach 1: (Using + operator)
One method is to create a string variable and then append the double value to the string variable. This will directly convert the double value to string and add it in the string variable.
Below is the implementation of the above approach:
Example 1:
class GFG {
public static String
convertDoubleToString( double doubleValue)
{
String stringValue = "" + doubleValue;
return (stringValue);
}
public static void main(String[] args)
{
double doubleValue = 1 ;
String stringValue;
stringValue
= convertDoubleToString(doubleValue);
System.out.println(
doubleValue
+ " after converting into string = "
+ stringValue);
}
}
|
Output:
1.0 after converting into string = 1.0
Approach 2: (Using String.valueOf() method)
The simplest way to do so is using valueOf() method of String class in java.lang package. This method takes the double value to be parsed and returns the value in String type from it.
Syntax:
String.valueOf(doubleValue);
Below is the implementation of the above approach:
Example 1:
class GFG {
public static String
convertDoubleToString( double doubleValue)
{
return String.valueOf(doubleValue);
}
public static void main(String[] args)
{
double doubleValue = 1 ;
String stringValue;
stringValue
= convertDoubleToString(doubleValue);
System.out.println(
doubleValue
+ " after converting into string = "
+ stringValue);
}
}
|
Output:
1.0 after converting into string = 1.0
