When in doubt, decompose (break into smaller parts) the problem!
You need to display a GUI.
You need to accept input from two widgets and convert it integers.
You need to add a range of numbers.
You need to concatenate a string of what you're doing with the addition.
You need to display an answer in a widget and maybe redraw the window.
I've been having success copying the assignment into my source file and decomposing it as comments to frame out my program.
Answer:
public class num9 {
public static void main(String[] args) {
int sum =0;
int num =5;
for(num =5; num<=500; num+=5){
System.out.println(num);
sum +=num;
}
System.out.println(sum);
}
}
Explanation:
- Declare and initialize the variables sum and num
- Use a for loop with the condition for(num =5; num<=500; num+=5) Since the loop will increment by 5 and run from 5 to 500
- Within the loop, add num to sum at each iteration
- Print all elements on seperate lines
- Outside the loop, print the final value of sum
Create a for loop
Answer:
The five factors to consider when trying to choose between a Solid State Drive, a Hard Disk Drive and, an External Hard Disk Drive are:
- Read/Write Speed
- Weight
- Power Consumption
- Cost
- Storage Capacity
- Solid State Drives (SSDs) are typically lighter in weight, faster and do not consume much power.
- Hard Disk Drives are relatively cheaper than SSDs. They also come with higher storage capacities but are more power-hungry and slower because they rely on mechanical/moving parts to read and write data.
- External HDDs are the cheapest of the three. They are not internal which is a major drawback given the additional weight. However, they come with gargantuan storage capacities that make you want to rethink having one. Besides, unlike SSDs, you can easily get them in computer accessories shops offline or online.
Cheers!
