下面是 toString() 方法的例子。

例子 1 :

// Java program to demonstrate// toString() method  import java.text.*;import java.util.*;import java.io.*;  public class GFG {    public static void main(String[] argv)    {        // creating and initializing Bidi        Bidi bidi            = new Bidi("Geeks",                       Bidi.DIRECTION_LEFT_TO_RIGHT);          // getting the internal state of bidi        // using toString() method        String status = bidi.toString();          // display the result        System.out.println("status of bidi : "                           + status);    }}

输出:

status of bidi : sun.text.bidi.BidiBase[  dir: 0   baselevel: 0  length: 5  runs: [0 0 0 0 0]  text: [0x47 0x65 0x65 0x6b 0x73]]

例2 :

// Java program to demonstrate// toString() method  import java.text.*;import java.util.*;import java.io.*;  public class GFG {    public static void main(String[] argv)    {        // creating and initializing Bidi        Bidi bidi            = new Bidi(                "TE1",                Bidi.DIRECTION_RIGHT_TO_LEFT);          // getting the internal state of bidi        // using toString() method        String status = bidi.toString();          // display the result        System.out.println(            "status of bidi : "            + status);    }}

输出:

status of bidi : sun.text.bidi.BidiBase[  dir: 2  baselevel: 1  length: 3  runs: [2 2 2]  text: [0x54 0x45 0x31]]
