How do you draw a square pattern in Java?

Step 1: Input number of rows and columns. Step 2: For rows of rectangle run the outer loop from 1 to rows. Step 3: For the column of the rectangle run the inner loop from 1 to columns. Step 4: Print star for first or last row or for first or last column, otherwise print blank space.

Do loops Java?

The Java do-while loop is used to iterate a part of the program repeatedly, until the specified condition is true. If the number of iteration is not fixed and you must have to execute the loop at least once, it is recommended to use a do-while loop. Java do-while loop is called an exit control loop.

How do I print numbers in a square pattern?

To print square number pattern, we need two loops. An outer loop to iterate through rows and second an inner loop to iterate through columns. Run an outer loop from 1 to total rows. The loop structure should look like for(i=1; i<=rows; i++).

What is the Java pattern program?

Java pattern program enhances the coding skill, logic, and looping concepts. It is mostly asked in Java interview to check the logic and thinking of the programmer. We can print a Java pattern program in different designs. To learn the pattern program, we must have a deep knowledge of the Java loop, such as for loop do-while loop.

How many loops are there in a Java pattern program?

Each pattern program has two or more than two loops. The number of the loop depends on the complexity of pattern or logic. The first for loop works for the row and the second loop works for the column. In the pattern programs, Java for loop is widely used. In the above pattern, the row is denoted by i and the column is denoted by j.

How do you design logic for a pattern program?

Whenever you design logic for a pattern program, first draw that pattern in the blocks, as we have shown in the following image. The figure presents a clear look of the pattern. Each pattern program has two or more than two loops. The number of the loop depends on the complexity of pattern or logic.

What are the different types of patterns that can be printed?

For example, it can be printing geometric figures (like triangles, squares, etc.), pyramids, boxes in various patterns of stars, numbers, and character styles on the console screen. The format or basic syntax of the loops may differ from one programming language to another, but the general logic to print these patterns remains the same.
