We’ll go over how to use for and while loops to print a hollow square star pattern in Java. This pattern is frequently used in programming exercises and is a great way to practice nested loops and conditional statements in Java. To demonstrate how to print the hollow square pattern in Java, we will provide an algorithm, pseudocode, and Java code for both for and while loops.<\/p>\n

What is Hollow Square Star Pattern in Java?<\/h2>\n

A hollow square pattern is one in which the square’s borders are printed with stars but the inside of the square is left blank.<\/p>\n

Algorithm to Print Hollow Square Star Pattern in Java<\/h3>\n
    \n
  1. Enter the number of rows.<\/li>\n
  2. An outer loop from 1 to N is used for rows.<\/li>\n
  3. An inner loop from 1 to N is used for columns.<\/li>\n
  4. Within the inner loop, print a star for the first and last row or column. <\/li>\n
  5. Which is the print star? <\/li>\n
  6. if i = 1 or i = N, or if j = 1 or j = N<\/li>\n
  7. Otherwise, print space is limited.<\/li>\n
  8. Print a blank line after the inner loop after printing all columns of a row.<\/li>\n<\/ol>\n
    Pseudo Code to Print Hollow Square Star Pattern using For Loop<\/h3>\n
    The following is the pseudocode for the provided Java code:<\/p>\n
      \n
    1. Request that the user enter the size of the square side.<\/li>\n
    2. Create a Scanner object to read the user’s input.<\/li>\n
    3. To see the Hollow Square Star Pattern, print the message.<\/li>\n
    4. To iterate over each row and column of the square, use nested for loops.<\/li>\n
    5. Determine whether the current row or column is the first or last row\/column.<\/li>\n
    6. If so, a star should be printed.<\/li>\n
    7. If not, print two blank spaces to make a hollow square.<\/li>\n
    8. To begin a new row, move the cursor to the next line.<\/li>\n
    9. The program has come to an end.<\/li>\n<\/ol>\n
