示例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

示例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); 
    }
