Fetch Decode Execute Simulation

Let's simulate the Fetch-Decode-Execute cycle, sometimes called the Machine Instruction Cycle.

This will help us review concepts related to:

• looping
• searching
• 1-dimensional arrays
• 2-dimensional arrays
• designing functions (with/without parameters)
• designing functions with/without return statements
• calling functions appropriately
• the Fetch-Decode-Instruction cycle

Let's slow things down! Include this line of code at the end of the for loop:

TimeUnit.SECONDS.sleep(1);

Replace some of the rows in the RAM array with null.

Does your program still work? What error do you get?

If there is an error, can you fix it?
