下面是一些例子来说明 isLeftToRight() 方法。

例子 1 :

// Java program to demonstrate// isLeftToRight() method  import java.text.*;import java.util.*;import java.io.*;  public class GFG {    public static void main(String[] argv)    {        // creating and initializing Bidi        // with base direction        Bidi bidi            = new Bidi(                "Geeks For Geeks",                Bidi.DIRECTION_LEFT_TO_RIGHT);          // checking both line and base direction        // using isLeftToRight() method        boolean status = bidi.isLeftToRight();          // display the result        if (status)            System.out.println(                "Both Line and Base "                + "direction is left to right");        else            System.out.println(                "Both Line and Base "                + "direction is not left to right ");    }}

输出:

Both Line and Base direction is left to right

例2 :

// Java program to demonstrate// isLeftToRight() method  import java.text.*;import java.util.*;import java.io.*;  public class GFG {    public static void main(String[] argv)    {        // creating and initializing Bidi        // with base direction        Bidi bidi            = new Bidi(                "Geeks For Geeks",                Bidi.DIRECTION_RIGHT_TO_LEFT);          // checking both line and base direction        // using isLeftToRight() method        boolean status = bidi.isLeftToRight();          // display the result        if (status)            System.out.println(                "Both Line and Base "                + "direction is left to right");        else            System.out.println(                "Both Line and Base "                + "direction is not left to right ");    }}
