ParsePosition getErrorIndex() method in Java with Example

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

public int getErrorIndex()

Parameter: This method does not accepts any argument as a parameter. Return Value: This method returns the index at which parse error may occur. Below are the examples to illustrate the getErrorIndex() method: Example 1:

Java

// Java program to demonstrate
// getErrorIndex() 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(0);

            // set index for the parsing error
            pos.setErrorIndex(3);

            // getting index at which
            // parsing error may come
            // using getErrorIndex() method
            int i = pos.getErrorIndex();

            // display result
            System.out.println(
                "index at which parse error may occur: "
                + Integer.toString(i));
        }

        catch (ClassCastException e) {

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

Output:

index at which parse error may occur: 3

Example 2:

Java

// Java program to demonstrate
// getErrorIndex() 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(0);

            // getting index at which
            // parsing error may come
            // using getErrorIndex() method
            int i = pos.getErrorIndex();

            // display result
            if (i != -1)
                System.out.println(
                    "index at which parse error may occur: "
                    + Integer.toString(i));
            else
                System.out.println("error index is not set");
        }

        catch (ClassCastException e) {

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

Output:

error index is not set
