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() methodimport 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( "index at which error occurred: " + 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() methodimport 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( "index at which error occurred: " + Integer.toString(i)); } catch (ClassCastException e) { System.out.println(e); } }} |
Output:
index at which error occurred: 3000
