  • Make a new project (but now n = 1) following these instructions
  • Name your class "Lab1". This happens when you are creating a new module, in the Java class name field
    • Add your name and section number in a comment before the class declaration
    • As explained in the subsections below, modify static void main() and create two other methods: static void countOccurrences() { ... } and static void printLayeredPyramid() { ... }
  • Submit your Lab1.java on Sakai by Monday, September 18

static void main(String[] args)

Your main() should do the following:

  • Ask the user (using println() or printf()) to input a single character c and a String S, each on separate lines. Read these with a Scanner object and pass them to countOccurrences().
  • Whatever value is returned by leapYearsInRange()
  • If a valid choice is made, call the corresponding function immediately. Otherwise print an error message
  • Let the program end (no loop -- just print prompt, read response, and execute one time)

static int countOccurrences(char c, String S)

Iterate through every character in the String S and count how many time char c occurs.

static void drawLayeredPyramid(int numLayers)

Draw the following pattern
