我這邊已經轉換型別了 ,別的都能轉換成功,就這個戶籍人口城鎮化率轉換不成功,怎么解決,求幫幫忙
if (hanshu.equals("AVG")) {
for (int i = 0; i < arrs.length-1; i++) {
if(arrs[i].equals("+") || arrs[i].equals("-") || arrs[i].equals("*") || arrs[i].equals("/")){
}else{
++avg;
zbz2=zbz2+Double.parseDouble(arrs[i]);
};
}
戶籍人口城鎮化率
0
+
戶籍人口城鎮化率
0

有人 幫幫忙嗎?uj5u.com熱心網友回復：
錯誤提示不是很清楚了嗎，你的parseDouble(arrs[i])出錯，因為arrs[i]是字串“戶籍人口城鎮化率”，不是Number型別，所以轉換出錯。所以，要自己判斷好arrs的資料再轉換（比如用正則判斷是否符合Number型別）或用try catch捕捉例外做相應的error handler。
