Code: import java.util.Scanner;
public class SuffixArray{
public static void main(String[] args){
Scanner stdIn = new Scanner(System.in);
String string1;
String[] array1;
int a;
System.out.print("String: ");
string1 = stdIn.nextLine();
a = string1.length();
for (int i=0; i<=a; i++){
array1[i] = string1.substring(i);}
array1.sort();
for (int i=0; i<=array1.length; i++){
System.out.println(array1[i]);}
}}
When I attempt to compile this I get the following error:
Code: cannot find symbol
array1.sort();
^
symbol: method sort()
location: variable array1 of type String[]
What am I doing incorrectly?
Edit by Merth: Moved to the General Programming sub forum.
According to
the Arrays class documentation Arrays.sort is a static (rather than instance) method, so try:
Code: Arrays.sort(array1);
It returns this:
Code: cannot find symbol
Arrays.sort(array1);
^
symbol: variable Arrays
location: class SuffixArray
If I comment out that line it says array1 wasn't initialized, and if I change it to the following it asks for an array dimension.
Code: array1 = new String[];
If I add any number as the dimension, it returns an error of not finding the variable array1.
The Java compiler isn't sure where to find "Arrays" - you need to show it that you mean java.util.Arrays by adding
Code: import java.util.Arrays;
to the top of your source file.

In many cases your life will be made easier by Code: import java.util.*;
I got all the errors worked out. Thanks for the assistance.
