Program on restroom

Program plan:

  • In a file “Restroom.java”, create a class “Restroom”,
    • Declare the Boolean array variable.
    • Define the constructor,
      • Assign the initial values.
    • Define a method “addOccupant()”,
      • Initialize the first stall in the longest unoccupied sequence.
      • Initialize the number of stalls in the longest unoccupied sequence.
      • Initialize the index of current sequence of unoccupied stalls.
      • Initialize the number of current sequence of unoccupied stalls.
      • Check whether the first stall is unoccupied,
        • If it is true, assign the values to start the sequence.
          • Create a loop to iterate over stalls,
            • Check whether the current stall is occupied,    
              • Check whether the run is end,
                • Assign the values.
            • Set the count to “0”.
            • Otherwise, check whether the user in the middle of a run of unoccupied stalls,
              • Increment the count, if it is true.
            • Otherwise, assign the values.
          • Check for the case when longest sequence is at the end,
            • Assign the values.
          • Assign the array value to true.
    • Define a method “getStalls()”,
      • Initialize the necessary string variable.
      • Create loop,
        • Check the condition,
          • Concatenate the string with “X”.
            • Otherwise,    
              • Concatenate the string with “_”.
      • Return the updated string.
  • In a file “RestroomTester.java”, create a class “RestroomTester”,
    • Define the method “main()”,
      • Initialize the variable for number of stalls.
      • Print the number of stalls.
      • Create the object for “Restroom”.
      • Call the method “addOccupant()”.
      • Print the value returned from the method “getStalls()”.
      • Print the expected occupied position.
      • Call the method “addOccupant()”.
      • Print the value returned from the method “getStalls()”.
      • Print the expected occupied position.
