Java Bidi baseIsLeftToRight()方法及示例

java.text.Bidi 类的 baseIsLeftToRight() 方法是用来检查这个Bidi实例是否有从左到右的基本方向。

语法

public boolean baseIsLeftToRight()

参数：这个方法不接受任何东西作为参数。

返回值： 如果这个bidi有 从左到右 的方向，这个方法返回真，否则返回假。

下面是一些例子来说明 baseIsLeftToRight() 方法。

例子 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
