Java Error code are the set of error that occurs during the compile-time and
Run-time. From java error we have given you a sample of code that makes
you to understand the java error code in a better way.
Understand with Example
In this Tutorial we want to describe you a code that help you in
understanding a Java error code. For this we have a class name 'Error code'. Inside
the main method we have an array list that is used to store when there is a
large variation in the amount of data to be taken. The array hold the constant
amount of data like number of month in a year, but unlike array list there
is no upper bound for the array list. The list is used to add integer as a
wrapper because array list never hold the primitive data in the try block. There
is a subsequent a catch block is after the try block to caught the exception occurred
in the try block.
On execution the given code, the prompt will show you an Null pointer exception, because
we do not specify the size of an array. This result in java error code.
JavaErrorCode
import java.util.*;
public class Errorcode {
public static void main(String[] args)
{
ArrayList list = null;
try {
list.add(1, new Integer(1));
} catch (Exception ex) {
System.out.println(ex);
}
}
}

Output
compile-single:
run-single:
java.lang.NullPointerException
BUILD SUCCESSFUL (total time: 0 seconds)
|
For removing this runtime error you have to specify the size of the Array.
