私は奇妙な問題があります。私のコードのIF条件が機能しません。条件が偽であってもif条件に入る。Android：IF条件が動作しない
デバッグモードで値を確認します。ここで
私のコードです：
for (int i = 0; i < Global.shopping_name.size(); i++) {
try {
double num;
long iPart;
double fPart;
String fractP = "";
// Get user input
num = Double.parseDouble(Global.shopping_ammount.get(i));
if(arrIngrName.contains(Global.shopping_name.get(i)));
{
// Get index of element
indx = arrIngrName.indexOf(Global.shopping_name.get(i));
if (arrIngrType.get(indx).equalsIgnoreCase(Global.shopping_type.get(i))) {
preValue = Double.parseDouble(arrIngrMeasure.get(i));
newValue = preValue + num;
num = newValue;
}
}
iPart = (long) num;
fPart = num - iPart;
System.out.println("Integer part = " + iPart);
System.out.println("Fractional part = " + fPart);

}
このコードは動作しません。
if(arrIngrName.contains(Global.shopping_name.get(i)));
{
// Get index of element
indx = arrIngrName.indexOf(Global.shopping_name.get(i));
if (arrIngrType.get(indx).equalsIgnoreCase(Global.shopping_type.get(i)))
{
preValue = Double.parseDouble(arrIngrMeasure.get(i));
newValue = preValue + num;
num = newValue;
}
}
とも私はそれがエラーを示しなステートメント他に追加します。
おかげ
..行の末尾から
;を削除し、以下の答えをフォローし、それが動作するはずです。 – Devaどうしたら 'if（arrIngrName.contains（Global.shopping_name.get（i）））;'行 –
はブロックを実行する前にif文が終了したため、 ';'を削除しました –
