Java 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，并代表当前bidi范围内的每个属性。

语法

public Bidi createLineBidi(int lineStart,                           int lineLimit)

参数 ：这个方法需要以下参数作为参数

返回值： 该方法返回一个新的Bidi 对象 。

下面是一些例子来说明 createLineBidi() 方法。

例子 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 : 5number of levels : 2Base 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 : 2number of levels : 1Base Level : 2
