long to String Conversion Example Java

April 26, 2011 | String and StringBuffer
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 many times to take any data type as parameter and converts into string; it converts even objects into strings. Now we study long to String.

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

public class LongToString
{
  public static void main(String args[])
  {
    long l1 = 10;
    String str = String.valueOf(l1);
    System.out.println("long l1 in string form is " + str);
  }
}

The long l1 is passed as parameter to valueOf() method. This method converts long l1 to string form. Anywhere l1 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 long can be done in Java.
