To avoid the infinity loop simply use a WaitHandle. To let the process be exited from the outer world use a EventWaitHandle with a unique string. Below is an example. If you start it the first time, it simple prints out a message every 10 seconds. If you start in the mean time a second … Read more
TL;DR The first example is an unintentional side-effect and will trigger rerenders unconditionally while the second is an intentional side-effect and allows the React component lifecycle to function as expected. Answer I think you are conflating the “Render phase” of the component lifecycle when React invokes the component’s render method to compute the diff for … Read more
I re-implemented your posted code with 2 screens, HomeScreen and SettingScreen and stripped out some part of the UiState class and its usages. The issue is in your HomeScreen composable, not in the StateFlow emission. You have this mutableState val uiState by viewModel.uiState.collectAsStateWithLifecycle( initialValue = UiState.Speak ) that is being observed in one of your … Read more
It is well defined behavior. In C11 a new clause 6.8.5 ad 6 has been added An iteration statement whose controlling expression is not a constant expression,156) that performs no input/output operations, does not access volatile objects, and performs no synchronization or atomic operations in its body, controlling expression, or (in the case of a … Read more
There is no difference in bytecode between while(true) and for(;;) but I prefer while(true) since it is less confusing (especially for someone new to Java). You can check it with this code example void test1(){ for (;;){ System.out.println(“hello”); } } void test2(){ while(true){ System.out.println(“world”); } } When you use command javap -c ClassWithThoseMethods you will … Read more

The problem is that “scanf()” can leave unread data in your input buffer. Hence the “infinite loop”. Another issue is that you should validate the return value from scanf(). If you expect one integer value … and scanf returns “0” items read … then you know something went wrong. Here is an example: #include <stdio.h> … Read more
Short answer You can check which View currently has the focus to distinguish between user and program triggered events. EditText myEditText = (EditText) findViewById(R.id.myEditText); myEditText.addTextChangedListener(new TextWatcher() { @Override public void onTextChanged(CharSequence s, int start, int before, int count) { if (myEditText.hasFocus()) { // is only executed if the EditText was directly changed by the user … Read more
There are a number of places where the language of the Standard gives compilers freedoms beyond what are required for useful optimizations, but which would instead provide compilers with ways to throw the Principle of Least Astonishment out the window. The way the rules about endless loops are written fits that category. Most of the … Read more
You have a semicolon after the condition. When you use braces to specify a block for your while you don’t use a semicolon.
