返回值

toString() 方法返回给定字符的字符串表示。

例子1

public class JavaCharacterToStringExample1 {
  public static void main(String[] args) {
      // Create two Character objects c1 and c2.
      Character c1, c2;
      // Assign the values to c1 and c2.
      c1 = new Character('r');
      c2 = new Character('9');
      // Create two String objects s1 and s2.
      String s1, s2;
      // Assign the String values of c1 and c2 to s1 and s2 respectively.
      s1 = c1.toString();
      s2 = c2.toString();
      String str1 = "The string value of " + c1 + " is:" + s1;
      String str2 = "The string value of " + c2 + " is:" + s2;
      // Print the values of str1 and str2.
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

输出：

The string value of r is:r
The string value of 9 is:9

例子2

public class JavaCharacterToStringExample2 {
  public static void main(String[] args) {
      // Create two Character objects c1 and c2.
      Character c1, c2;
      // Assign the values to c1 and c2.
      c1 = new Character('A');
      c2 = new Character('7');
      // Create two String objects s1 and s2.
      String s1, s2;
      // Assign the String values of c1 and c2 to s1 and s2 respectively.
      s1 = c1.toString();
      s2 = c2.toString();
     // Print the values of str1 and str2.
      System.out.println("The string value of " + c1 + " is:" + s1);
      System.out.println("The string value of " + c2 + " is:" + s2);
     
   }
}

输出：

The string value of A is:A
The string value of 7 is:7

例子1

public class JavaCharacterToStringExample_1 { 
   public static void main(String[] args) {
    // Create two char primitives ch1 and ch2.
      char ch1, ch2;
    // Assign the values to ch1 and ch2.
      ch1 = 'V';
      ch2 = 118;
    // Create two String objects s1 and s2.
      String s1, s2;
    // Assign the String values of ch1 and ch2 to s1 and s2.
      s1 = Character.toString(ch1);
      s2 = Character.toString(ch2);
      String str1 = "The string value of " + ch1 + " is given as:" + s1;
      String str2 = "The string value of " + ch2 + " is given as:" + s2;
    // Print the values.
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

输出：

The string value of V is given as:V
The string value of v is given as:v

例子2

public class JavaCharacterToStringExample_2 {
   public static void main(String[] args) {
    // Create two char primitives ch1 and ch2.
      char ch1, ch2;
    // Assign the values to ch1 and ch2.
      ch1 = 'f';
      ch2 = 'e';
    // Create two String objects s1 and s2.
      String s1, s2;
    // Assign the String values of ch1 and ch2 to s1 and s2.
      s1 = Character.toString(ch1);
      s2 = Character.toString(ch2);
      String str1 = "The string value of " + ch1 + " is given as:" + s1;
      String str2 = "The string value of " + ch2 + " is given as:" + s2;
    // Print the values.
      System.out.println( str1 );
      System.out.println( str2 );
   }
}
