Adding the last element to string after array

Adding the last element to string after array

My storage string gives me all the digits in want besides the last, I know
its because the last digit has nothing to compare to the right. Can I add
the last digit to the end of my string somehow,
for(int i = 0;i < othercontent.length -1 ;i++ )
{
if(othercontent[i] != othercontent[i + 1])
{
storage = storage + othercontent[i];
}
}
