Question

I need to convert a string vector in a simple string. I do not know how to proceed.
I tried various solutions such as

for(int i=1; i < easy.length; i++){

easyPuzzle = easy[i].toString();

}

System.out.println(" " + easyPuzzle);

but this solution prints only the ith element and not the entire string vector.

Answer 1

You keep reassign a new value to easyPuzzle when you really want to concatenate:

easyPuzzle += easy[i].toString();

If easy.length is large, it might make sense to use a StringBuilder which is more efficient at concatenating than String:

StringBuilder builder = new StringBuilder();
for(int i=1; i < easy.length; i++){
    builder.append(easy[i].toString());
}
easyPuzzle = builder.toString();

Also by starting your for loop at i=1 you exclude the first item. Not sure if it is on purpose or not. If not, start at i = 0.

Alternatively, to save the pain of writing the loop yourself, you can use @Manoj’s answer which replaces your code by one line.
