Answer 1

hey there steve
import java.util.*; public class Genric<E> { public static void main(String[] args) { Map<String, Integer> unique = new LinkedHashMap<String, Integer>(); for (String string : "House, House, House, Dog, Dog, Dog, Dog".split(", ")) { if(unique.get(string) == null) unique.put(string, 1); else unique.put(string, unique.get(string) + 1); } String uniqueString = join(unique.keySet(), ", "); List<Integer> value = new ArrayList<Integer>(unique.values()); System.out.println("Output = " + uniqueString); System.out.println("Values = " + value); } public static String join(Collection<String> s, String delimiter) { StringBuffer buffer = new StringBuffer(); Iterator<String> iter = s.iterator(); while (iter.hasNext()) { buffer.append(iter.next()); if (iter.hasNext()) { buffer.append(delimiter); } } return buffer.toString(); } }

Answer 2

This is one of the difficult questions in Java. Because It is easy to write in C.

import java.util.Scanner;

class Brainly

{

public static void main(String args[])
{
int num = 0;

System.out.println("Enter a String");

Scanner demo = new Scanner(System.in);

String hell = demo.nextLine().toLowerCase();

for(char i = 'a';i<='z';i++)

{

for(int j=0;j<hell.length();j++)

{

if(hell.charAt(j)==i)

{

num++;

}

}

if(num!=0)

{

System.out.println(i+"="+num);

num=0;

}

}

}

}



Output:

Enter a string: steeve.

s = 1

t = 1

e = 3

v = 1.
