Full Pyramid (Compact)\n"); for (int i = 0; i < rows; i++) { System.out.println(String.join("", Collections.nCopies(5 - i - 1, " ")) + String.join("", Collections.nCopies(2 * i + 1, "*"))); } // java 8 System.out.println("\n4. Inverted Pyramid\n"); for (int i = rows; i > 0; i--) { System.out.println(String.join("", Collections.nCopies(5 - i, " ")) + String.join("", Collections.nCopies(2 * i - 1, "*"))); } } }

[answering from head] I thing it have to do something with that "package" thing. Your main is in the class CreatePyramid, witch isn't projects main class so your main doesn't get called. Just try removing the package line and name .java file same as class
