Bidi getRunStart() method in Java with Examples

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 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 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);
    }
}

Output:

start of run for index 0 is : 0
