variables

问题 This question already has answers here : How are static variables with the same name in different functions identified by the System? (3 answers) Closed 6 years ago . I have tried running and compiling the code where I have defined the static variables with the same name in two different source files. The code was compiled successfully and running. Now my question is that both the static variables reside in the . data/BSS section in the memory. As per my understanding two different memory

问题 I have code in which I have a large number of characters all declared as being 1 higher than the other. e.g. m1, m2, m3... is there any way to increase the number I'm searching for by 1 in a for loop? I have a long string of letters that I need to check to see if any of them match to the individual, but I cannot use strings due to situational limitations. a1 is the particular character I'm looking for, m1 is the first in a long string of characters I am having to store as individuals My

In the code my integer "Memes" is saying that it might not have been initialized and that a local variable hides in field. private void totalUpdate(int yes){ if (yes==1){ int CompBot = Integer.parseInt(lblbotComp.getText()); int CompTop = Integer.parseInt(lbltopComp.getText()); int CompMid = Integer.parseInt(lblmidComp.getText()); int Memes = Memes + CompBot + CompTop + CompMid; lbltotalComp.setText(

问题 I would like to call an object method dynamically. The variable "MethodWanted" contains the method I want to execute, the variable "ObjectToApply" contains the object. My code so far is: MethodWanted=".children()" print eval(str(ObjectToApply)+MethodWanted) But I get the following error: exception executing script File "<string>", line 1 <pos 164243664 childIndex: 6 lvl: 5>.children() ^ SyntaxError: invalid syntax I also tried without str() wrapping the object, but then I get a "cant use +

问题 Got a quick question which I hope someone can answer. Basically I have a String variable which needs changing based upon the value in a combo box which has an event listener attached to it. However if I make the string final then it cant be changed, but if i don't make it final then eclipse moans that it isn't final. Whats the best (and simplest) work around?
