Chapter 6, Problem 30RE

Explanation of Solution

The given code:

//iterate a for loop using loop variable “i” up to “i<=height”.

for (int i = 1; i <= height; i++)

{

/*iterate a for loop using loop variable “j” up to “i<=width”.*/

    for (int j = 1; j <= width; j++)

    {

        //prompt a “*”

        System.out.print("*");

    }

//new line

System.out.println();

}

Explanation:

The above code snippet is used to illustrate the use of nested loops. In the code,

• Iterate a “for” loop using loop variable “i” up to the condition “i<=height”.
  • Iterate a “for” loop using loop variable “j” up to a condition “j <= width”.
    • Prompt a “*”.
  • Create a new line using print statement.

Equivalent code using single “for” loop:

//define a class nestedLoop

public class nestedLoop

{

    //define main() method

    public static void main(String[] args)

    {

        //iterate a for loop up to “I <= 3”.

        for (int i = 1; i <= 3; i++)

        {

/*create an integer variable j and initialize with “1”...
