Java 中的 Bidi getBaseLevel()方法，带示例

原文:https://www . geesforgeks . org/bidi-getbaselevel-method-in-Java-with-examples/

java.text.Bidi 类的 getBaseLevel() 方法用来获取这个 Bidi 类实例的基级别。基本级别是指此 Bidi 实例的基本级别是“从左到右”还是“从右到左”。

语法:

public int getBaseLevel()

参数:这个方法不接受任何东西作为参数。

返回值:此方法用于提供 0 表示从左到右的基本级别，1 表示从右到左的基本级别。

以下是说明 getLength() 方法的示例:

例 1:

// Java program to demonstrate
// getBaseLevel() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        // creating and initializing Bidi
        Bidi bidi = new Bidi("Geeks for Geeks", 0);

        // getting base level
        // using getBaseLevel() method
        if (bidi.getBaseLevel())
            System.out.println("Base level is "
                               + "right to left");
        else
            System.out.println("Base level is "
                               + "left to right");
    }
}

输出:

Base level is right to left

例 2:

// Java program to demonstrate
// getBaseLevel() 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_LEFT_TO_RIGHT);

        // getting base level
        // using getBaseLevel() method
        if (bidi.getBaseLevel())
            System.out.println("Base level is "
                               + "right to left");
        else
            System.out.println("Base level is "
                               + "left to right");
    }
}

输出:

Base level is left to right
