Solution to
Try It Yourself: loops

    1. Loops 1, 2, 5, 6
    2. Loops 3, 4
    3. Loops 3, 4, 6
    4. Loop 4
    5. Loops 1, 2, 4, 6
    6. Loops 3, 5


  2. one
two
two
zero
three



  3. int input;
do {
  input = inputBox.getInteger();
} while ((input % 4 != 0) && (input % 7 != 0));



  4. // first print the top row
for (int i = 0; i < col; i++)
    outputBox.print("*");
outputBox.skipLine(1);
   
// print the middle
for (int r = 1; r < row - 1; r++) {
    outputBox.print("*");
    for (int c = 1; c < col - 1; c++)
        outputBox.print(" ");
    outputBox.printLine("*");
}

// print the last row
for (int i = 0; i < col; i++)
    outputBox.print("*");
outputBox.skipLine(1);
