Flood map

Program plan:

• In a file “FloodMap.java”, import necessary package and create a class “FloodMap”,
  • Define a method “printFloodMap()”,
    • Create a loop,
      • Create an inner loop,
        • Check the condition,
        • • If it the condition is true, print a “*” and a space.
        • Otherwise,
        • • Print a space.
  • Define a method “lowest()”,
    • Assign the first array value as minimum.
    • Create a loop,
      • Create an inner loop,
        • Check the condition,
        • • If it is true, assign the value to minimum.
    • Return the minimum value.
  • Define a method “highest()”,
    • Assign the first array value as maximum.
    • Create a loop,
      • Create an inner loop,
        • Check the condition,
        • • If it is true, assign the value to maximum.
    • Return the maximum value.
  • Define a method “read()”,
    • Create Scanner object.
    • Create a loop,
      • Create an inner loop,
        • Get the value from the user.
• In a file “FloodMapTester.java”, create a class “FloodMapTester”,
  • Define the method “main()”,
    • Create the object for “FloodMap”.
    • Prompt the user a height value.
    • Declare 2D array.
    • Call the method “read()”.
    • Assign the value returned from the method “lowest()”.
    • Assign the value returned from the method “highest()”.
    • Initialize the steps.
    • Create loop,
      • Call the method “printFloodMap()”.
