Java 安卓：如果条件不起作用

我有一个奇怪的问题。如果代码中的条件不起作用。即使条件为false，它也会进入if条件

我在调试模式下检查这些值

这是我的密码：

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);

另外，当我添加else语句时，它会显示错误

谢谢你保留了分号在if语句末尾。首先删除它。

因为IF语句末尾有分号

      if(arrIngrName.contains(Global.shopping_name.get(i)));

---

删除

从行尾开始。
按照下面的答案进行操作，它应该会起作用。如果（arrIngrName.contains（Global.shopping_name.get（i）），这个
怎么办行删除
因为if语句在执行块之前终止
      if(arrIngrName.contains(Global.shopping_name.get(i)));

if(arrIngrName.contains(Global.shopping_name.get(i)));
