I'm quite new to Java and having an issue checking null element in integer array.
I'm using Eclipse for editor and the line that checks null element is showing error:
Line that complains:
if(a[i] != null) {
Error msg from Eclipse:
The
operator != is undefined for the argument type(s) int, null
In PHP, this works without any problem but in Java it seems like I have to change the array type from integer to Object to make the line not complain (like below)
Object[] a = new Object[3];
So my question is if I still want to declare as integer array and still want to check null,
what is the syntax for it?
Code:
public void test() {
int[] a = new int[3];
for(int i=0; i<a.length; i++) {
if(a[i] != null) { //this line complains...
System.out.println('null!');
}
}
}
