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
