How do I check if two strings have the same characters?

Method 2 (Count characters)

1. Create count arrays of size 256 for both strings. Initialize all values in count arrays as 0.

3. Compare count arrays. If both count arrays are same, then return true.

How do you compare two strings in a for loop?

Use the equals() method to check if 2 strings are the same. The equals() method is case-sensitive, meaning that the string “HELLO” is considered to be different from the string “hello”. The == operator does not work reliably with strings. Use == to compare primitive values such as int and char.
