Nested for loop Problem

Question

public class Loopa{
public static void main(String[] args){

char[] trouble = {'t', 'r', 'o', 'b', 'l', 'e'};
char[] bubble = {'b', 'u', 'b', 'b', 't', 'e'};

int numberOfSameCharacters = 0;

for(int i = 0; i < trouble.length; i++){
for(int j = 0; j < bubble.length; i++){
if(trouble[i] == bubble[j]){
numberOfSameCharacters++;
}
}
}

}
}

It's giving me this error
Exception in thread "main" java.lang.ArrayIndexOutBoundsException: Index 6 out of bounds for length 6
at Loopa.main(Loopa.java:11)

Answer 1

I think your second loop should be like this
for (int j = 0; j < bubble.length; j++)
You wrote i++ as the increment instead of j++

Answer 2

Can't believe i made this mistake

thank you @Agent_l
