Java中的 Bidi baseIsLeftToRight() 方法及示例

Java.text.Bidi类的baseIsLeftToRight()方法用于检查此Bidi 实例是否具有从左到右的基本方向。

句法：

public boolean baseIsLeftToRight()

参数：此方法不接受任何参数。

返回值：此方法返回true ，如果此bidi 具有从左到右的基本方向，否则返回false。

以下是说明getLength()方法的示例：

示例 1：

// Java program to demonstrate
// baseIsLeftToRight() 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 base direction
        // using baseIsLeftToRight() method
        boolean status
            = bidi.baseIsLeftToRight();
  
        // display the result
        if (status)
            System.out.println(
                "Base direction is "
                + "left to right");
        else
            System.out.println(
                "Base direction is "
                + "right to left");
    }
}

输出：

Base direction is left to right

示例 2：

// Java program to demonstrate
// baseIsLeftToRight() 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(
                "Tajmahal",
                Bidi.DIRECTION_RIGHT_TO_LEFT);
  
        // checking base direction
        // using baseIsLeftToRight() method
        boolean status
            = bidi.baseIsLeftToRight();
  
        // display the result
        if (status)
            System.out.println(
                "Base direction is "
                + "left to right");
        else
            System.out.println(
                "Base direction is "
                + "right to left");
    }
}

输出：

Base direction is right to left
