Check the following code and use a loop instead of many ifs. import java.util.Scanner; //main method declared public class rinoel_Program1 { public static void main(String[] args) { int sales[]=new int[5]; Scanner in = new Scanner(System.in); for(int i = 0; i < sales.length; ++i) { //while loop declared for repeatation while(true) { System.out.print("Enter today’s sales for stores "+ (i+1) +": "); sales[i] = in.nextInt(); //condition to check for negative number if(sales[i]<0) { System.out.println("enter the sales amount until a positive amount is entered");System.out.print("\nEnter today’s sales for stores "+ (i+1) +": "); sales[i] = in.nextInt(); } break; } } System.out.println(); //display bar chart System.out.println("Sales Bar Chart"); for(int i = 0; i < 5; ++i) { System.out.printf("Store %d: ", i+1); if(i == 0) { bar(sales[i]); } if(i == 1) { bar(sales[i]); } if(i == 2) { bar(sales[i]); } if(i == 3) { bar(sales[i]); } if(i == 4) { //bar method bar(sales[i]); } } } public static void bar(int n) { for(int i = 0; i < n / 100; ++i) { System.out.print("*"); if(i<0) { System.out.print("OOPS! you have entred negative value plz enter the positive value @"); } else System.out.print(" "); } System.out.println(); } }
