default: System.out.println(input.nextInt()+ " is not a valid charachter , please try again");
}//end of while loop
}Sorry im new to this,i have a code there im now developing sorting algo. in my code the user provide a size of the array between 5 to 30 then the user will choose if he/she wants to supply the numbers between 1to100 or these are generated randomly. My problem is that if the user difine the array size, then after the array size given it will ends the loop up to 30. all i want is if the user difine array size 5 only 5 index will prompt. please help im also trying here any advise?

Answer 1

thanks for the reply. my code now works on the problem:) but the bubblesort method not performing its task. how can i call the bublesort method to sort my values in the array?
case 2 : System.out.println("Please provide the size of the array between 5 to 30; ");
                                        int num = 0;
                                        int arrays = input.nextInt();
                                        for(int i = 0; i <=arrays; i++){
                                 System.out.println("If you want to supply the number between 1 to 100 press 1,or\n2 to generate it ramdomly: ");
                                    switch (input.nextInt()){
                                        case 1: int[] arrSize = new int[arrays];
                                                for(int i = 0; i <=arrSize.length; i++){
                                                    arrSize[i] = num;
                                                    System.out.println("Please enter number on index"+i+":");
                                                    num=input.nextInt();
                                        break;
                                        case 2: int[] arr = new int[arrays];
                                                Random random = new Random();
                                                for (int idx = 1; idx <= arr.length; ++idx){
                                                int randomInt = random.nextInt(100);
                                                arr[idx - 1] = randomInt;
                                                System.out.println(Arrays.toString(arr));
                                                System.out.println("\n");
                                        System.out.println("What Sorting algorithm you want to ferform?\n1. Bubble Sorting \n2. Selection Sorting\n3. Insertion\n");
                                            switch (input.nextInt()){
                                                case 1 : new Main().bubbleSort(x);     
                                                break;
