The getRunLevel() method of java.text.Bidi class used to provide the level for the nth run of this line of text if there is only one running state then It will provide base level for that state . Syntax:
public int getRunLevel(int run)
Parameters: This method accepts the index of the logical run for which the level of the run is to be retrieved. Return Value: This method provides the level for the particular run in the line of text. Below are the examples to illustrate the getRunLevel() method: Example 1:Â
Java
// Java program to demonstrate// getRunLevel() methodÂ
import java.text.*;import java.util.*;import java.io.*;Â
public class GFG {    public static void main(String[] argv)    {        // creating and initializing Bidi        Bidi bidi            = new Bidi(                "Geeks For Geeks",                Bidi.DIRECTION_RIGHT_TO_LEFT);Â
        // index for which level is needed        int index = 0;Â
        // getting the level of run        // using getRunLevel() method        int level = bidi.getRunLevel(index);Â
        // display the result        System.out.println(            "level of first run is : "            + level);    }} |
Output:
level of first run is : 2
Example 2:Â
Java
// Java program to demonstrate// getRunLevel() methodÂ
import java.text.*;import java.util.*;import java.io.*;Â
public class GFG {    public static void main(String[] argv)    {        // creating and initializing Bidi        Bidi bidi            = new Bidi(                "Geeks For Geeks",                Bidi.DIRECTION_LEFT_TO_RIGHT);Â
        // index for which level is needed        int index = 0;Â
        // getting the level of run        // using getRunLevel() method        int level = bidi.getRunLevel(index);Â
        // display the result        System.out.println(            "level of first run is : "            + level);    }} |
Output:
level of first run is : 0
