Java示例在方法中使用Label

public class NewClass {

   public static void main(String[] args) {

      String strSearch = "This is the string in which you have to search for a substring.";

      String substring = "substring";

      boolean found = false;

      int max = strSearch.length() - substring.length();

      testlbl: for (int i = 0; i <= max; i++) {

         int length = substring.length();

         int j = i;

         int k = 0;

         while (length-- != 0) {

            if(strSearch.charAt(j++) != substring.charAt(k++)){

               continue testlbl;

            }

         }

         found = true;

         break testlbl;

      }

      if (found) {

         System.out.println("Found the substring .");

      } else {

         System.out.println("did not find the substing in the string.");

      }

   }

}
