# data[].attributes.body
comment the code segment in the "static void main" method
//testIntegerLimitsLoop4()

add new code section the method "testIntegerLimitsLoop5a()

Execute the code.

# data[].attributes.body
Well you get the picture:
Comment out the code //testIntegerLimitsLoop4()
and add the code testIntegerLimitsLoop5();

Execute the code......

# data[].attributes.body
Type the code as captured in the screenshot below the section/method testIntegerLimits3();

Comment out the code in the main sections  for
// testIntegerLimits3();

add the code like testIntegerLimits3();

# data[].attributes.body
Important: Comment the code that you do not want to run as shown in the screen shot.

Also add the line as shown in Line 9 to test the new code testIntegerLimits3().

# data[].attributes.attachment_caption
Important: Pay attention to the case sensitivity of the code. Java is a case-sensitive programming language. 

# data[].attributes.body
This time type the code as shown in the screenshot:
Pay attention for every open brace "{" there has to be a close "}" brace. It sections the code to various parts or scopes.

Step 3: Create a break Point for debugging

Step 3: Create a break Point for debugging

Important: Read all the commented lines in the code. It is important to put or add comments in your code. It is called the best practices.

Now Execute the code by clicking the Context Run | Debug controls at the beginning of the "static void main" code sections as shown in the screenshot.

# data[].attributes.body
Now to test the Function "testIntegerLimits2"
Note: the code lines 13-33 has been folded
First, Comment the line 3, by putting two forward slashes "//"  inline-3.
Add the Line: 8 testIntegerLimits2); in the "main functions"
Your code should look like the screenshot.

Step 1:...... Continuation from part 1 of the assignment

Make sure your code for Week2.java looks like the above screenshot:

Now add the following Code in the sections highlighted "Add Your code here"

// Sction Start

// you need to have an unique method name if your code is in the same segment. That makes commonsense right?

public static void testIntegerLimits2() {

//Step 1: Declare the variable type

Integer a; //   the line here declares the type Inter is a Data Type in Java and "a" is a variable. So that the computer can reserve some memory.

// at this point the value stored in the variable is undertenant.

//Step 2: You need to assign a value

a = 100;

Print("Before:");

Print(a);

//Step 2a: Increase the value of a by 10;

a = a +10; // this may seem odd

// reasoning the computer will create a temp variable internally and store the value of "a +10"

// then reuse the variable "a" to store the value of the result "a +10"

//Step 3: Use the following code to print the value in the variable a

Print("After:");

Print(a);

}
