Compare two strings of ints in java

Question

I have two Strings that contain numbers and I want to see if the second string contains the same numbers as the first String, whether they are in order or not. If it has any number repeating than report false. Is there anyway in java other than using .charAt() because its not working for number after 10?

String one = "1 2 3 4 5 "; 
String two = " 3 2 1 4 5 ";
String three = "3 2 1 4 4 "; 

Answer 1

Looks like homework. So these steps you can follow:

• Trim both strings
• Convert both strings into ArrayList using space separator
• Sort both arrays numerically
• Compare both arrays

Answer 2

You can use Scanner.nextInt() to read numbers from the string, add them to a Set, and see if set1.equals(set2) is true.
