Java valueOf () method

Java String class

There are several different forms valueOf () method:

• valueOf (boolean b): Returns a string representation of the boolean argument..

• valueOf (char c): Returns a string representation of the char argument.

• valueOf (char [] data): Returns a string representation of the char array argument form.

• valueOf (char [] data, int offset, int count): String Returns the char array argument of a particular sub-array representation.

• valueOf (double d): Returns a string representation of the double argument.

• valueOf (float f): Returns a string representation of the float argument.

• valueOf (int i): int Returns a string representation of the argument.

• valueOf (long l): Returns a string representation of the long argument.

• valueOf (Object obj): Returns a string representation of the Object argument.

Examples

public class Test {
    public static void main(String args[]) {
    	double d = 1100.00;
        boolean b = true;
        long l = 1234567890;
        char[] arr = {'r', 'u', 'n', 'o', 'o', 'b' };

        System.out.println("返回值 : " + String.valueOf(d) );
        System.out.println("返回值 : " + String.valueOf(b) );
        System.out.println("返回值 : " + String.valueOf(l) );
        System.out.println("返回值 : " + String.valueOf(arr) );
	}
}

The above program execution results:

返回值 : 1100.0
返回值 : true
返回值 : 1234567890
返回值 : w3big
