Use for loops to generate the patterns. All chosen character should be printed by a single statement of the form System.out.print( chosenChar ); //chosenChar is a char type variable, the value input by user With this statement in a loop it causes the chosen character to print side by side. A statement of the following form can be used to move to the next line. System.out.println(); A statement of the following form can be used to display a space. There should be no other output statements in the program. System.out.print( ); Problem-Solving Tips 1. The diamond could be split into three parts: the top triangle, the middle line (the number of characters is the size of the diamond), and the bottom triangle. 2. For the top and bottom triangles, you should decide how many white spaces to print before the first character and how many characters to print. Use nested for loops: outer for loop is for rows, two inner for loops, one to print white spaces, one to print characters. 3. Use a for loop for the middle line (the code has been given). 4. If you have any questions as you proceed, ask your lab instructor for help.
