Split string into several two character strings

Question

I have this string 8S8Q4D1SKCQC2C4S6H4C6DJS2S1C6C

How can I split this string into substrings that consist of 2 characters per substring? I\'m confused

Answer 1

System.out.println(Arrays.toString(
    "8S8Q4D1SKCQC2C4S6H4C6DJS2S1C6C".split("(?<=\\G.{2})")
));

Answer 2

Use the substring(int beginIndex, int endIndex) method of the String class.

Answer 3

You will have to do a split like this on your own. You could use something like substring in the following way:

public String[] customSplit(String src, int size) {
    Vector<String> vec = new Vector<String>();

    for(int i = 0; i < src.length(); i += size) {
        vec.add(src.substring(i, (i+size > src.length()) ? src.length() : i+size);
    }

    return vec.toArray(); 
}

Answer 4

for (int i = 0; i < a[2].Length; i++)
{
    string ss = (8S8Q4D1SKCQC2C4S6H4C6DJS2S1C6C).Substring(i, 2);
    Console.Write(ss);
    i++; 
}
