assertion

• If a Java class contains assert statements, then it must be compiled with -source 1.4 option.
• When a program having assert is run, -ea or -enableassertion option must be specified, otherwise the assertions get ignored.
• If the logical expression evaluates to false, then the program generates an AssertionError
• The program terminates on its first AssertionError.
• The condition in assert statement must be followed by a semi-colon.
