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 ");
    }
}

输出:

Both Line and Base direction is not left to right
