无法在Eclipse中观看Java本地类实例

Question

Here is a small sample:

public class LocalClassSample {
    public static void main(String[] args) {
        class Utils {
            public void printHello(String name) {
                System.out.println("Hello " + name);
            }
            public String outHello(String name) {
                return "hello " + name; 
            }
        }

        Utils util = new Utils();
        util.printHello("World");
    }
}

I put a break point at the last line. I am able to view util in the Variables window...

I try to view the same variable in the expressions window...it is unable to evaluate:

Update:

Even tried inspecting the variable in the Display View...it does not evaluate:

Answer 1

Expression eval a java expression like 'util.printHello("World")' and return the result ("Hello World"). 'util' is not an 'expression' but just a variable name, if you want to inspect it, use the Variables view or the Inspect command.
