下面是说明isLeftToRight()方法的示例：

示例 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

示例 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
