Java valueOf() Method

Java String类Java String Class

The valueOf() method has the following different forms:

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

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

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

  • valueOf(char[] data, int offset, int count):Returns the string representation of a specific subarray of the char array argument.

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

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

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

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

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

Syntax

static String valueOf(boolean b) 

或 

static String valueOf(char c) 

或

static String valueOf(char[] data) 

或

static String valueOf(char[] data, int offset, int count) 

或

static String valueOf(double d) 

或

static String valueOf(float f) 

或

static String valueOf(int i)

或

static String valueOf(long l)

或

static String valueOf(Object obj)

Parameters

  • Specified type parameter.

Return Value

Returns the string representation of the parameter type.

Example

Example

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(Return Value : + String.valueOf(d) );
        System.out.println(Return Value : + String.valueOf(b) );
        System.out.println(Return Value : + String.valueOf(l) );
        System.out.println(Return Value : + String.valueOf(arr) );
    }
}

The output of the above program is:

返回值 : 1100.0
返回值 : true
返回值 : 1234567890
返回值 : example
