Last Updated : 27 Nov, 2019

The getRunStart() method of java.text.Bidi class used to provide the index of the first character where the nth run starts for this Bidi instance. Syntax:

public int getRunStart(int run)

Parameters: This method accepts the index of the logical run for which start of the run is to be retrieved. Return Value: This method provides the index of start character for the nth logical run. Below are the examples to illustrate the getRunStart() method: Example 1:

Java

// 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);
    }
}

Output:

start of run for index 0 is : 0

Example 2:

Java

// 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);
    }
}
