Question

Need help coding with Java. Explanation in code would be greatly appreciated. Thanks

Bar graph 2.0 Write a program that accepts a list of up to 100 integers and displays a bar graph showing the frequencies of the values and the corresponding percentage frequency distributions (printed to 1 significant digit). Example runs are shown below. Number of values to graph: Enter the integer values separated by a space: Bar graph for 3 #1111# 01110 100.01 umber of integers to readi Enter the integer values separated by a spaces 1 1 113 2 Bar graph for 1 3 2: i 0 66.7 16.74 16.7 Note that spaces should be included to the end of each row when the final value is not large enough to warrant an '#' at that height.

import java.util.Scanner;

public class Main

        System.out.println("Number of value to the graph: ");
        Scanner in = new Scanner(System.in);
        int n=in.nextInt();
        int a[]=new int[n];
        int b[]=new int[100];//stores number of occurances of each number
        int sum=0;//to calculate frequency
        System.out.print("Enter the integer values seperated by space: ");
        for(int i=0;i<n;i++)
        {
            a[i]=in.nextInt();//taking input
            b[a[i]]++;
        }

        int max=0;
        System.out.print("Bar graph for ");//printing first line
        for(int i=0;i<100;i++)
        {
            sum=sum+b[i];
            if(b[i]>0)

        }
        System.out.println();
        int x=max;
        
        /*logic for printing # is that max number should have # from first line
        where as remaining should have from the line of (max-their value)*/
        
        for(int i=0;i<x;i++)
        {
            System.out.print("  ");
            for(int j=1;j<100;j++)

                if(b[j]>=max)
                    System.out.print("# # # # # #  ");
                else
                    System.out.print(" ");
            }
            max--;
            System.out.println();
        }

        for(int i=0;i<100;i++)
            if(b[i]>0)
                System.out.print("-------------");
        System.out.println();

        for(int i=0;i<100;i++)
            if(b[i]>0)
                System.out.print("            "+i);
        System.out.println();

        for(int i=0;i<100;i++)
            if(b[i]>0)
            {
                double k=(double)b[i]*100/sum;
                String s = String.format("%.2f",k);
                System.out.print("        "+s);
            }

    }
