My teacher wants me to put a while loop into my program, where do I put it for the best outcome? public static void main(String[] args) { int min = 19; int num1=0, num2=0, num3=0; int tol1=0, tol2=0, tol3=0; int max = 50; int col[]=new int[49]; for(int i = 0; i < 49; i++){ int ran = (int)(Math.random() * (max - min + 1) + min); if( ran <= 20 && ran < 30){ num1 += 1; tol1 += ran; } if(ran <= 30 && ran < 40){ num2 += 1; tol2 += ran; } if(ran <= 40 && ran < 50){ num3 += 1; tol3 += ran; } col[i]= ran; } for(int i = 0; i < 49; i++ ){ if(i == 7 || i == 14 || i == 21 || i == 28 || i == 35 ||i == 42){ System.out.println("\n"); } System.out.printf(("%7d"),+ col[i]); } System.out.printf("\n"); System.out.printf("Found "+ num1 +" number(s) in the 20s "+ "totaling "+ tol1); System.out.printf("\nFound "+ num2 +" number(s) in the 30s "+ "totaling "+ tol2); System.out.printf("\nFound "+ num3 +" number(s) in the 40s "+ "totaling "+ tol3); } }
