I have this program which is supposed to be stuck in an infinite loop at line 12. But it doesn't, instead it prints 5. It only behaves correctly (i.e runs infinitely) when I run it in debug mode.
It never gets in the first loop starting at line 6, which is the intention.  Am I missing something?

public class WierdLoop {  public static void main(String[] args)  {    int number = 10;        while (number > 10) {            number--;        }        do {            number++;            while (number > 5){                number++;            }        }  while (number < 5);        System.out.println("number  " + number);  } }

Try using the Hibernate session which is not that memory intensive.

When you have the tests that affect the structure of the database. You must always roll back after executing the test. As a rule of thumb, your test must test the existing structure, not alter it.

You can have a look at the Java Tutorials - RMI to review about the Java RMI.

For a quick review on Lambdas, you can checkout the following Java 8 Lamdba basics

I would say, do it. Even if its not for credits, do it regardless. The lessons learned from that experience will be invaluable. It will also teach you how to work in a team...which is exactly what you will be doing in real world projects.

Put what you have leaned so far into practice. Write more java code. pick a small project to work on.

I would suggest that you use normal notepad and use the command line. Don't use the IDE until you are able to figure how to compile the program on the command line.
It will help clear a lot of things by the time you switch to the IDE.

this refers to the instance of the current object.

when you have the setter method as below public void setB(int b){this.b=b;}

You are seting the value that is passed as the paramete to the instance variable b

The getter method below is simply returning the value of the instance variable.

public int getB(){return b;}

You can use the Rest Template if you are familiar with Spring.

This article gives a brief overview of the rest template.

I agree with Peter, make use of the documentation as it is comprehensive and more frequently updated.

I think the confusion is caused by some text books which actually teach that java is pass by reference on Object types and pass by value on primitive types.

Much appreciated! I will be more careful next time... And thank you for spoting that mistake.
