Lacks Conditional Statement<\/h1>\n

The answer to the mistake in your program is that it’s an unending loop. It’ll always be true because you just asked the value of accountNum<\/code> and didn’t add conditional statement.<\/strong><\/p>\n

Use this code below as replacement to your code and it works.<\/p>\n

import java.util.Scanner;\n\npublic class Yehey {\n    public static void main(String[] args) {\n        int accountNum = 1;\n        double cMeter;\n        double pMeter;\n        double eUsage;\n        double totalDueAmount = 0.0;\n        double Tot = 0.0;\n        Scanner input = new Scanner(System.in);\n\n        while (true) {\n\n            \/\/ user enter account no\n            System.out.print(\"Enter Account number (0 to stop ) : \");\n            accountNum = input.nextInt();\n            if (accountNum==1) {\n                \/\/ user enter current meter reading\n                System.out.print(\"Current meter reading : \");\n                cMeter = input.nextDouble();\n                \/\/ user enter previous meter reading\n                System.out.print(\"Previous meter reading : \");\n                pMeter = input.nextDouble();\n                eUsage = cMeter - pMeter;\n                System.out.print(\"Electricity Usage(in kWh) : \" + eUsage);\n                System.out.println();\n\n                if (eUsage >= 1 && eUsage <= 200) {\n                    totalDueAmount = 0.218 * eUsage;\n                } else if (eUsage > 200 && eUsage <= 300) {\n                    totalDueAmount = 0.334 * eUsage;\n                } else if (eUsage > 300 && eUsage <= 600) {\n                    totalDueAmount = 0.516 * eUsage;\n                } else if (eUsage > 600 && eUsage <= 900) {\n                    totalDueAmount = 0.546 * eUsage;\n                } else {\n                    totalDueAmount = 0.571 * eUsage;\n                }\n                System.out.println();  \/\/ total amount for the account is displayed\n                System.out.println(\"Amount number : \" + accountNum + \",\" + \" your charge is \" + \"RM\" + totalDueAmount);\n                Tot = totalDueAmount++;\n                System.out.println();\n\n                \/\/ loop exit and displa the total amount for all accounts\n                System.out.println(\"Total Amount collected  = \" + \"RM\" + Tot);\n                System.out.println(\"________________________________\");\n                System.out.println(\"--- DONE ----\");\n                System.out.println(\"________________________________\");\n            } else {\n                System.out.println(\"Thank you for using my program.\");\n                break;\n            }\n        }\n    }\n}\n<\/code><\/pre>\n
Added changes:
\n1. Changed the inside condition of while to true<\/code>
\n2. Added if statement to execute code if accountNum remains 1 and breaks the program if its value changed to other values.
\n3. Added…System.out.println(\"Thank you for using my program.\"); break;<\/code> if the value of accountNum is not equal to zero<\/p>\n
(Note: Please clarify what your problem or question is to avoid having your question be flagged or have down votes.)<\/em><\/p>\n<\/p><\/div>\n
