如何操纵数组

Question

如何操纵for循环，问题在于评论 如何重新进入for循环并动态添加索引，除了自动增量。

for (int i = 0; i < words.size(); i++)
{             
try {
     temp = QueryWithContext.query(words.get(i));
     if((temp == null || temp.isEmpty()) && words.size() > i+1)
      {
        QueryWithContext.query(words.get(i)+" "+words.get(i+1));
        temp = QueryWithContext.query(words.get(i)+" "+words.get(i+1));
        System.out.println("1st if");
        //if condition = true, the codes below must not run anymore 
        //and for loop will increment by 1 except for the auto inc
        if((temp == null || temp.isEmpty()) && words.size() > i+2)
         {
            System.out.println("2nd if");
            temp = QueryWithContext.query(words.get(i)+" "+                                                                    
                                     words.get(i+1)+" "+words.get(i+2));
            //if condition = for loop will increment by 2 
            //except for the auto inc
         }
      }
    }
 }

如果您的意思是增加循环索引，则可以增加代表索引的i值。 i += 2;应该做的工作。当循环结束并重新开始时，它最终将增加3。
