返回值 ：该方法提供了第n个逻辑运行的起始字符的索引。

下面是说明 getRunStart() 方法的例子。

例1 :

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

输出:

start of run for index 0 is : 0

例2 :

// Java program to demonstrate
// getRunStart() 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", 1);
  
        int index = 0;
  
        // getting the start of run for the index 0
        // using getRunStart() method
        int level = bidi.getRunStart(index);
  
        // display the result
        System.out.println(
            "start of run for index 0 is : "
            + level);
    }
}

输出:
