Java Bidi toString()方法及示例

java.text.Bidi 类的 toString() 方法是用来显示这个Bidi实例的字符串表示。

语法

public String toString()

参数 ：这个方法不接受任何东西作为参数。

返回值 ：该方法以 字符串格式 显示bidi的内部状态 。

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]]
