Why am I getting so many errors in my code?

[namenamename]

import java.util.*;
import java.io.*;
 
class arraysort{
	public static void main(String args[]) throws Exception{
		int index,number=0;			
		Scanner input = new Scanner(new File("wordlist.txt"));
		String words[] = new String[100];
		String max,k;
 
		int a[];
		for(int i=0;i<words.length;i++){
		   number = (int)(Math.random()*10);
		   for (int j=0;j<number;j++){
		     words[j] = input.nextLine();
		}
 
		for (int c=0;c<99;c++){
           {
		     max = a[c];
		     for (int j=c+1;j<100;j++)
			   {
			     if (a[j].compareTo(max)>0)
				   {
				     max = a[j];
					 index = j;
				   }
			   }
			 k = a[c];
			 a[c] = a[index];
			 a[index] = k;
		    }
		}
	  }
 
	}
}

Errors are:

max = a[c];

if (a[j].compareTo(max)>0)

How do I resolve these errors?

Take them one at a time.

The error that says int cannot be dereferenced means that you're trying to use the dot operator on an int, which is a primitive. Think about exactly what you're trying to do; there is a simpler way than trying to call a method on a primitive.

The errors about incompatible types means that you're trying to store a String value in an int variable, or an int value in a String value, or something similar. There are functions in the String and Integer classes that might help with conversions.

Also, fix your indentations, which should help you match up parenthesis.
