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
