Question

Write a program that fill two arrays rad[10] and len[10] by random generator (numbers between 0 and 100). rad[] array represents the (radius) of Cylinder, and array len[] represents length of the cylinder. Then using the two arrays, compute the volume of the cylinder and put the result in another array vol[10]. Then find the maximum volume and print it and its radius and length.

Sample Run:

The radiuses are: 2 99 29 4 1 78 23 56 3 6

The lengths are: 2 3 2 9 6 5 4 2 6 55

The volumes are: 25.12 92325.42 5281.48 452.16 18.84

95518.80 6644.24 19694.08 169.56 6217.20

Explanation / Answer

import java.util.Random;

public class cylinder {
    static float vol(int rad, int len){
        return (float)3.14*rad*rad*len;
    }
    public static void main(String[] args) {
        int rad[]=new int[10];
        int len[]=new int[10];
        float vol[] = new float[10];
        float max=0;
        int maxrad=0;
        int maxlen=0;
        Random rand = new Random();
        for(int i=0;i<10;i++){
            rad[i] = rand.nextInt(100);
            len[i] = rand.nextInt(100);
            vol[i] = vol(rad[i],len[i]);
            if(vol[i]>max){
                max=vol[i];
                maxrad=rad[i];
                maxlen=len[i];
            }
        }
        System.out.print("The radiuses are:");
        for(int i:rad){
            System.out.print(" "+i);
        }
        System.out.print(" ");
        System.out.print("The lengths are:");
        for(int i:len){
            System.out.print(" "+i);
        }
        System.out.print(" ");
        System.out.print("The volumes are:");
        for(float i:vol){
            System.out.print(" "+i);
        }
        System.out.print(" ");
        System.out.println("Maximum volume is= " + max + "and its radius=" +maxrad + ",length="+maxlen);
    }

}
