ParsePosition getErrorIndex() method in Java with Example

Last Updated : 22 Jan, 2020

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 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 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); 
        } 
    } 
}
