I have three Java assignments that I need to be completed as soon as possible, all of them involve around methods/ArrayList if you can help me with these it would be greatly appreciated.

import java.util.Scanner;
class Q2
{
public static void printSpaces(int count)
{
for(int i = 0; i < count; ++i)
System.out.print(" ");
}
public static void fun(String title, String topic, String author)
{
int alen = title.length();
int blen = topic.length();
int clen = author.length();
int maxlen = alen;
if(maxlen < blen)
maxlen = blen;
if(maxlen < clen)
maxlen = clen;

for(int i = 0; i < maxlen + 4; ++i)
System.out.print("*");
...
