Java中的 Bidi getBaseLevel() 方法及示例

Java.text.Bidi类的getBaseLevel()方法用于获取该Bidi 类实例的基础级别。基本级别是指此 Bidi 实例是否具有“从左到右”或“从右到左”的基本级别。

句法：

public int getBaseLevel()

参数：此方法不接受任何参数。

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

以下是说明getLength()方法的示例：

示例 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

示例 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
