Java Bidi getRunLevel()方法及示例

java.text.Bidi 类的 getRunLevel() 方法用于提供这一行文字的第n次运行的级别，如果只有一个运行状态，它将提供该状态的基本级别。

语法

public int getRunLevel(int run)

参数：该方法接受要检索的 逻辑运行 的级别的索引。
返回值： 该方法提供了文本行中特定运行的级别。下面是说明 getRunLevel() 方法的例子：

例1 :

// Java program to demonstrate
// getRunLevel() 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",
                Bidi.DIRECTION_RIGHT_TO_LEFT);
 
        // index for which level is needed
        int index = 0;
 
        // getting the level of run
        // using getRunLevel() method
        int level = bidi.getRunLevel(index);
 
        // display the result
        System.out.println(
            "level of first run is : "
            + level);
    }
}

输出

level of first run is : 2

例2 :

// Java program to demonstrate
// getRunLevel() 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",
                Bidi.DIRECTION_LEFT_TO_RIGHT);
 
        // index for which level is needed
        int index = 0;
 
        // getting the level of run
        // using getRunLevel() method
        int level = bidi.getRunLevel(index);
 
        // display the result
        System.out.println(
            "level of first run is : "
            + level);
    }
}

输出
