java.lang.String valueOf(double d)
Description :
This java tutorial shows how to use the valueOf(double d) method of String class of java.lang package. This method returns a string representation of double data type. This will yield the same result as Double.toString(double).
Method Syntax :
public static String valueOf(double d)
Parameter Input :
| DataType | Parameter | Description |
|---|---|---|
| double | d | method parameter which we are interested to get the string equivalent |
Method Returns :
The String valueOf() method with argument double returns a new String object which corresponds to the string representation of the method argument.
Compatibility Version :
Since the beginning
Exception :
None
Discussion :
The string valueOf(double d) method is simply to get a String equivalent of float method parameter. This method be statically accessed which means we should call the method like String.valueOf(double d).
Java Code Example :
This example source code demonstrates the use of valueOf(double d) of String class. Below are different examples of getting a value of double. As you would noticed we have used the unboxing functionality to transform a Double object into double primitive datatype and then get the string equivalent using the valueOf method.
package com.javatutorialhq.java.tutorial.string;
/*
* Java example source code to get the value of primitive double data type
*/
public class StringValueOfFloat {
public static void main(String[] args) {
// primitive double declaration
double val = 1.0123;
// Object of Double data type
Double valueDouble = 100.125123;
System.out.println(String.valueOf(val));
System.out.println(String.valueOf(valueDouble));
System.out.println(String.valueOf(123.123123));
}
}
Sample Output :
Running the valueOf() method example source code of String class will give you the following output
java string indexOf(double) method example
