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 program to demonstrate
// setErrorIndex() 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(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 program to demonstrate
// setErrorIndex() 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(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
