java - 从数组生成变量以创建循环

Question

所以我有一个在从文本文件读取和拆分变量时生成的数组。然后，我需要将数组中的拆分变量解析为整数，并将其包含在 try catch 中，以防数据不是整数。我试图避免为数组中的每个变量创建 try catch block 。这是我到目前为止的代码:

String [] tempList = data.split("-");

String [] variables = {"readerNo", "seconds", "minutes", "hours", 
                       "days", "month", "year", "other","empNo"};
int readerNo, seconds, minutes, hours, days, month, year,other, empNo;
/*
* parsing of data to integers/boolean
*/

//-----------
for(int i = 0; i < variables.length; i++) {
    try{
        *variable name should be here* = Integer.parseInt(tempList[i]); 
    }catch(Exception E){
        *variable name should be here* = -1; 
    }
}

是否可能或者我需要为每个创建一个 try catch block ？

Answer 1

尝试这样做:

int[] myNumbers = new int[tempList.length];
for(int i = 0; i < tempList.length; i++){
  try{
     myNumbers[i] = Integer.parseInt(tempList[i]); 
  }catch(Exception E){
     myNumbers[i] = -1; 
  }
}

这就是避免 try{}- block 的方法:)
