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);        }    }} |
Output:
error index is not set
