float to String Conversion Example Java

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 wit.h valueOf() static method. valueOf() is overloaded to take any data type as parameter and converts into string; it converts even objects into strings. In this tutorial we convert float to String

The following program does the job of converting float to String.

public class FloatToString
{
  public static void main(String args[])
  {
    float f1 = 10.5f;              // observe, float initialization
    String str = String.valueOf(f1);
    System.out.println("float f1 in string form is " + str);
  }
}

The float f1 is passed as parameter to valueOf() method. This method converts float f1 to string form. Anywhere f1 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.

t1.setText(str);

where t1 is an object of TextField.

A string can also be converted to byte, short, int, long, float, double, char and boolean.

Note: The other way, string to float can be done in Java.
