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.
- Iterate a “for” loop using loop variable “j” up to a condition “j <= width”.
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”...
