• 

  问题描述

  如何使用方法重载打印不同类型的数组？
• 

  解决方案

  此示例说明如何在循环中出现 break 或 continue 语句时跳转到特定标签。

  
  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.");
        }
     }
  }
  

• 

  结果

  上面的代码示例将产生以下结果。

  
  Found the substring .
