how to convert a string into int array

Question

for eg. INPUT: string st="123";

Answer 1

In Java you can use something like that :

public class Program
{
public static void main(String[] args) {
String st = "123";
int[] array = new int[3];
for (int i = 0; i < 3; i++ ){
array[i] = (st.charAt(i));
System.out.println(array[i]-48);
}

}
}

Use the length of the String and so on.

Ok you you are getting chars type from your String. The char value for 1 is 49, for two 50 and so on...
