Program Plan Intro

Random walk

Program plan:

• Include the required header files.
• Define the “Random_Walk” class
  • Define the main method.
    • Declare an object for “Random” class.
    • Create an object for the “DrawingPanel” class.
    • Call the method “walk()” with the arguments.
• Define the “walk” method.
  • Declare the required variables with the values
  • Create an object for “Graphics” class
  • Set the color
  • Draw the oval
  • Iterate “i” until it reaches “steps” value
    • Check the result of “getDistance” method value is greater than 100 or not.
      • If the condition is true, then break the loop.
        • Otherwise,
        • • Call the “drawRect” method with the arguments
          • Call the “getDirection” method with an argument and store the result in “move” variable
          • Check the “move” value is equal to 1
            • Calculate the “yCenter” value.
          • Check the “move” value is equal to 2
            • Calculate the “xCenter” value.
          • Check the “move” value is equal to 3
            • Calculate the “yCenter” value
          • Otherwise, calculate the “xCenter” value
          • Call the “sleep” method
• Define the “getDirection” method
  • Return the random value
• Define the “getDistance” method
  • Return the distance.
