Java String.split() Method Example

This is a complete example to demonstrate the usage of split()  methods.

public class SplitExample {
    public static void main(String[] args) {
        String str = "java,guides.net";
        String[] strArray = str.split(",");
        for (int i = 0;
        i <
         strArray.length;
        i++) {
            System.out.println(strArray[i]);
        }
        strArray = str.split(",", 0);
        for (int i = 0;
        i <
         strArray.length;
        i++) {
            System.out.println(strArray[i]);
        }
    }
}
