.valueOf()

The .valueOf() method returns the string representation of a given value.

Syntax

String.valueOf(value)

The .valueOf() method is static and is called directly from the String class.

The value parameter can be one of the following data types:

• int
• long
• float
• double
• boolean
• char

Example

The following is an example of the .valueOf() method being applied to values of different data types:

// Main.java
public class Main {
  public static void main(String[] args) {
    // Concatenating an integer with string
    int x = 20;
    String str = "22";
    System.out.println(String.valueOf(x) + str);

    // String representation of boolean argument
    boolean b = true;
    System.out.println(String.valueOf(b));

    // Concatenating string with float
    float f = 4.66f;
    System.out.println(str + String.valueOf(f));

    // Char to String
    char ch = 'A';
    System.out.println(String.valueOf(ch));
  }
}

This will produce the following output:

2022
true
224.66
A
