Apr 8, 2025 · In many Java interviews Star, number, and character patterns are the most asked Java Pattern Programs to check your logical and coding skills. Pattern programs in Java help you to sharpen your looping concepts (especially for loop) and problem-solving skills in Java.

This page shows the list of Java Number Pattern Programs using for loop, while loop, functions, and class examples.

These 10 Java number pattern programs cover various patterns such as triangles, pyramids, diamonds, and more. By practicing these patterns, you can improve your understanding of loops and nested loops in Java, as well as develop problem-solving skills related to pattern printing.

Mar 22, 2014 · Your inner for loop for (int j = (rows + 1 - i) ; j > 0 ; j-- ){ System.out.print(j); } will always count down to 1, because it keeps going until j is zero. Also, the number that the current row starts on will depend on the current row, because you used i in your assignment to j. To get pattern 1 both of those things will have to change.

Jun 13, 2024 · Employ a nested loop structure, with one loop iterating through rows and another for printing numbers within each row. Print the row index (i) the corresponding number of times within each row.

Jul 5, 2022 · Number Pattern helps one form different patterns in Java, such as star patterns, character patterns, etc., using conditional loops and syntaxes in Java. Before moving to Number Pattern Program in Java, let's see how we can understand the pattern.

In this Java pattern program, we show the steps to print the number in an X pattern using for loop, while loop, and functions. The below program accepts the user-entered rows and uses the nested for loop and if else to traverse the rows and columns.
