ParsePosition setErrorIndex() method in Java with Example

Last Updated : 02 Feb, 2022

The setErrorIndex() method of java.text.ParsePosition class is used to set the index at which parse error may occur.
Syntax:

public void setErrorIndex(int ei)

Parameter: This method takes integer ei as a parameter at which parse error may occur.
Return Value: This method has nothing to return.
Below are the examples to illustrate the setErrorIndex() method:
Example 1:

Java

// Java program to demonstrate
// setErrorIndex() 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 the parsing error
            // using setErrorIndex() method
            pos.setErrorIndex(3);

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

            // display result
            System.out.println(
                &quot;index at which error occurred: &quot;
                + Integer.toString(i));
        }

        catch (ClassCastException e) {

            System.out.println(e);
        }
    }
}

Output:

index at which error occurred: 3

Example 2:

Java

// Java program to demonstrate
// setErrorIndex() 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 the parsing error
            // using setErrorIndex() method
            pos.setErrorIndex(3000);

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

            // display result
            System.out.println(
                &quot;index at which error occurred: &quot;
                + Integer.toString(i));
        }

        catch (ClassCastException e) {

            System.out.println(e);
        }
    }
}
