Java Programming exercise:
- Create a class called Collatz
- Create the main method
- Inside, create these variables:
- Create an int called collatzNum and assign it any positive integer from 1-100 (Please refer to the PE Clarification Thread on Ed for example output.)
- Create an int called numSteps and assign it 0. The number of “steps” corresponds to the number of times you apply one of the operations.
- Create an int called highestNumReached and assign it the value collatzNum
- Create an int called initValue and assign it the value collatzNum
- Create a while loop that terminates when collatzNum is equal to 1 6. Within the while loop, use an if-else statement to do the following:
- If collatzNum is even, collatzNum should be assigned half of its current value
- Otherwise, (if it’s odd), collatzNum should be three times its value plus one.
- Check whether the new collatzNum is greater than If so, update its value to collatzNum
- Print out collatzNum and add 1 to numSteps
- Close the while loop
- After the while loop, use three print statements to output:
- “Initial value: [initValue]”
- “Number of steps: [numSteps]”
- “Highest number reached: [highestNumReached]”
- Finally, use a switch statement to print one of the following statements according to the value of numSteps:
- 0 steps: “No steps required”
- 1 step: “Only took one step!”
- 2 steps: “Two steps”
- 3 steps: “Three steps”
- 4 steps: “Four steps”
- All other amounts: “Wow, [numSteps] steps was a lot of steps!” (For example, if 8 steps were taken, “Wow, 8 steps was a lot of steps!” should be printed without the quotes.)

My Code:

public static void main(String[] args){
/**
*@param numStep.
*/
Random r = new Random();
int collatzNum = r.nextInt(100) + 1;
int numSteps = 0;
int highestNumReached = collatzNum;
int initValue = collatzNum;
/**
* Prints collatzNum.
*/
System.out.println(collatzNum);
/**
*
* While loop that computes equation.
*/
while (collatzNum != 1) {
if (collatzNum %= 2)
collatzNum = collatzNum * 2;
}
else if (collatzNum %= 1){
collatzNum = 3 * collatzNum + 1;
}
else (collatzNum > highestNumReached) {
highestNumReached = collatzNum;
}
System.out.println(collatzNum);
numSteps ++;
}
/**
* Printing statments.
*/
System.out.println("Initial Value: " + initValue);
System.out.println("Number of steps: " + numSteps);
System.out.println("Highest number reached: " + highestNumReached);
/**

* Switch statement for numSteps.
*/
switch (numSteps) {
case 0:
System.out.println("No steps required!");
break;
case 1:
System.out.println("Only took one step!");
break;
case 2:
System.out.println("Two steps!");
break;
case 3:
System.out.println("Three steps!");
break;
case 4:
System.out.println("Four steps!");
break;
default:
System.out.println("Wow, " + numSteps + " steps was a lot of steps!");
}
}
}

How would I do the loop without importing anything? I'm not supposed to import any packages for this exercise. Thank you
