Error in code when using assertion

[Hemant Agarwal]

  class A 
{
  void m1(int i) 
{
    int j = i % 3;
    switch (j) 
{
      case 0: System.out.print("0"); break;
      case 1: System.out.print("1"); break;
      default:
        assert j == 2;
        System.out.print(j);
  }
}
        public static void main (String[] args) 
{
    A a = new A();
    for (int i=5; i >= -1; i--) {a.m1(i);}
}
}  

Now when I tried to compile it this error is coming. I don't know what is its meaning.

A.java:11: warning: as of release 1.4, assert is a keyword, and may not be used
as an identifier
assert j == 2;
^
A.java:11: ';' expected
assert j == 2;
^
1 error
1 warning

I posted this in the beginners form and
I got an answer from Mr. Bastin
Hi Hemant,

While compiling, use "-source 1.4" option.

For Example: If your filename is Abcd.java, compile as
"javac -source 1.4 Abcd.java". You will get the compilation right.

Now how to do this inside an eclipse?

In the compiler preferences, disable "default compliance settings" and set the "source compatibility" to 1.4.

My problem has been solved.
