ParsePosition setIndex() method in Java with Example

Last Updated : 22 Jan, 2020
The setIndex() method of java.text.ParsePosition class is used to set the current parse position of this ParsePositon object . Syntax: 
public void setIndex(int index)
Parameter: This method takes integer index at which current parse position is going to be set. Return Value: This method has nothing to return. Below are the examples to illustrate the setIndex() method: Example 1: Java 
// Java program to demonstrate
// setIndex() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {

            // Creating and initializing
            // new ParsePosition Object
            ParsePosition pos
                = new ParsePosition(1);

            // set index for current
            // Parse Position object
            // using setIndex() method
            pos.setIndex(3);

            // getting the current
            // ParsePosition of
            int i = pos.getIndex();

            // display result
            System.out.println(
                "current parse position: "
                + Integer.toString(i));
        }

        catch (ClassCastException e) {

            System.out.println(e);
        }
    }
}
Output: 
current parse position: 3
Example 2: Java 
// Java program to demonstrate
// setIndex() method

import java.text.*;
import java.util.*;
import java.io.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {

            // Creating and initializing
            // new ParsePosition Object
            ParsePosition pos
                = new ParsePosition(500);

            // set index for current
            // Parse Position object
            // using setIndex() method
            pos.setIndex(30);

            // getting the current
            // ParsePosition of
            int i = pos.getIndex();

            // display result
            System.out.println(
                "current parse position: "
                + Integer.toString(i));
        }

        catch (ClassCastException e) {

            System.out.println(e);
        }
    }
}
Output: 
current parse position: 30
