Converting String to Int in Java using Arrays

I'm trying to convert the string values to integers, however whenever i do this, it gives me the ASCI value of the character instead of the actual typed string.

Example:

a user inputs "11101" on there keyboard to a string variable named binary

for(int i = 0; i < binary.length(); i++){
storage[i] = Integer.valueOf(binary.charAt(i));
}

if I look at the values of storage[i], i will see only the ASCI values of the numbers, and not the actual 1's or 0's

for(int i = 0; i < binary.length(); i++){
    storage[i] = binary.charAt(i) - '0';
}

Use Integer.parseInt(str,radix) method.

int no=Integer.parseInt("11101",2);

//or

int no=Integer.parseInt("11101");

Try this:

for(int i = 0; i < binary.length(); i++){
    storage[i] = Integer.valueOf(binary.substring(i, i + 1));
}

This should do the trick. 

storage[i] = Integer.parseInt( binary.charAt(i));
