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
