Java中的 Bidi createLineBidi() 方法及示例

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。

句法：

public Bidi createLineBidi(int lineStart,
                           int lineLimit)

参数：此方法将以下参数作为参数

• lineStart : 它是这个新的比迪酒的起点
• lineLimit : 这是这个新比迪酒的终点

返回值：此方法返回一个新的Bidi 对象

下面是说明createLineBidi()方法的示例：

示例 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

示例 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
