原文:https://www . geesforgeks . org/bidi-createlinebidi-method-in-Java-with-examples/

java.text.Bidi 类的 createLineBidi() 方法用于创建一个新的 Bidi 对象，该对象具有相同的基本方向，并表示范围内当前 Bidi 的每个属性。

语法:

public Bidi createLineBidi(int lineStart,
                           int lineLimit)

参数:该方法以下列参数为参数

  • Line starting point : This is the new Bidi.
  • Line terminal : It is this new Bidi.

的终点

返回值:这个方法返回一个新的 Bidi 对象

以下是说明 createLineBidi() 方法的示例:

例 1:

// Java program to demonstrate
// createLineBidi() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing Bidi
        // text with base direction
        Bidi bidi
            = new Bidi(
                "Geeks For Geeks",
                Bidi.DIRECTION_RIGHT_TO_LEFT);

        // creating and new bidi Object using the old one
        // using createLineBidi() method
        Bidi newbidi = bidi.createLineBidi(1, 6);

        // display the new bidi status
        System.out.println("New Bidi "
                           + "\nLength : "
                           + newbidi.getLength()
                           + "\nnumber of levels : "
                           + newbidi.getRunCount()
                           + "\nBase Level : "
                           + newbidi.getBaseLevel());
    }
}

输出:

New Bidi 
Length : 5
number of levels : 2
Base Level : 1

例 2:

// Java program to demonstrate
// createLineBidi() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing Bidi
        // text with base direction
        Bidi bidi
            = new Bidi("Tajmahal",
                       Bidi.DIRECTION_RIGHT_TO_LEFT);

        // creating and new bidi Object using the old one
        // using createLineBidi() method
        Bidi newbidi = bidi.createLineBidi(3, 5);

        // display the new bidi status
        System.out.println("New Bidi "
                           + "\nLength : "
                           + newbidi.getLength()
                           + "\nnumber of levels : "
                           + newbidi.getRunCount()
                           + "\nBase Level : "
                           + newbidi.getBaseLevel());
    }
}

输出:

New Bidi 
Length : 2
number of levels : 1
Base Level : 2
