如何在 Java 中使用方法過載列印不同型別的陣列

問題描述

如何使用方法過載列印不同型別的陣列？

解決方案

此示例展示瞭如何在一個迴圈中跳到特定標籤，當出現 break 或者 continue 語句時。

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.");
      }
   }
}

結果

上述程式碼樣例將產生以下結果。

Found the substring .
