assert

[J Brewer]

With the following code:

  public class Test {

public static void main (String[] args) {
int iAge = 1;
assert(iAge == 0); System.out.println("String");
System.out.println("well well");
 }
 
}  

When I run the following code, it compiles but I get the AssertionError, as expected. However, "String" does not output, as the K&B book woud suggest. So, do I have it correct when I think that, in this example, if the assert expression results in true, then "String" and "well well" are both output, but if the expression results in false, then neither print out and I automatically get an Assertion Error?

The way you have it set up, you end the assert statement with the semicolon, and the SOP line is just another line.

You need to have a : after the assert condition, but you can't have a void method after the :.

You can do this.

public class Test {

public static void main (String[] args) {
int iAge = 1;
assert(iAge == 0): "String";
System.out.println("well well");
 }
 
}

Thankyou, thankyou. I did not even notice my syntax error. Everything is running as it should now.
