double to String Conversion Example Java

Summary: By the end of this tutorial "Data type double String Conversion", you will come to know to convert double to string.

We know earlier, parsing is the operation on strings to convert into data types. This parsing, we used in command-line arguments and User Password validation. Now we think the other way. Sometimes, it is required to convert data types to string; exactly opposite of parsing. For this purpose, the String class comes with valueOf() static method. valueOf() is overloaded to take any data type as parameter and converts into string; it converts even objects into strings.

The following program does the job of Data type double to String Conversion

public class DoubleToString
  public static void main(String args[])
    double d1 = 10.5;
    String str = String.valueOf(d1);
    System.out.println("double d1 in string form is " + str);

The double d1 is passed as parameter to valueOf() method. This method converts double d1 to string form. Anywhere d1 is required as string, str can be used. For example, to display anything thing in TextField, it must be in string form. Now str can be displayed in TextField as follows.


where t1 is an object of TextField.
