示例 1

public class CharactercharValueMethodExample1 {
  public static void main(String[] args) {		
   // Create the first character object.
       Character char1 = new Character('A');
       System.out.print("The character value of char1 is = ");
       System.out.println(char1.charValue()); 
   // Create the second character object.
       Character char2 = new Character('B');
       System.out.print("The character value of char2 is = ");
       System.out.println(char2.charValue());
    }
}

输出

The character value of char1 is = A
The character value of char2 is = B

示例 2

public class CharactercharValueMethodExample2 {
	public static void main(String[] args)
	{
	  // Create five Character object a, b, c, d and e
		Character a = new Character('1');
		Character b = new Character('2');
		Character c = new Character('3');
		Character d = new Character('4');
		Character e = new Character('5');
      // assign the primitive value to the five character.
		char ch1 = a.charValue();
		char ch2= b.charValue();
		char ch3= c.charValue();
		char ch4= d.charValue();
		char ch5= e.charValue();
    // print the primitive char value
		System.out.println("The primitive char value of a is: " + ch1);
		System.out.println("The primitive char value of b is: " + ch2);
		System.out.println("The primitive char value of c is: " + ch3);
		System.out.println("The primitive char value of d is: " + ch4);
		System.out.println("The primitive char value of e is: " + ch5);
	}
}

输出

The primitive char value of a is: 1
The primitive char value of b is: 2
The primitive char value of c is: 3
The primitive char value of d is: 4
The primitive char value of e is: 5

示例 3

public class CharactercharValueMethodExample3 {
	public static void main(String[] args)
    {
        // Create a character object
        Character x1 = new Character('z');
        Character x2 = new Character('e');
        Character x3 = new Character('r');
        Character x4 = new Character('o');        
        // assign the primitive value to a character
        char ch1 = x1.charValue();
        char ch2 = x2.charValue();
        char ch3 = x3.charValue();
        char ch4 = x4.charValue(); 
        System.out.println("Primitive char value is " + ch1);
        System.out.println("Primitive char value is " + ch2); 
        System.out.println("Primitive char value is " + ch3);
        System.out.println("Primitive char value is " + ch4);
        System.out.println(ch1+"   "+ch2+"    "+ch3+"    "+ch4);
        }
}

输出

Primitive char value is z
Primitive char value is e
Primitive char value is r
Primitive char value is o
z   e    r    o
