Java 中的 Bidi baseIsLeftToRight()方法，带示例

原文:https://www . geeksforgeeks . org/bidi-baseislefttoright-method-in-Java-with-examples/

java.text.Bidi 类的base islettoright()方法用于检查这个 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:如果此比迪已经向左到向右基本方向，则此方法返回真否则返回假。

以下是说明 getLength() 方法的示例:

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

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
