2. 分析为何将变量'result'初始化为'null'可能是冗余的 在Java等编程语言中,全局变量默认会被初始化为null(对于对象类型)或相应的默认值(对于基本数据类型)。对于局部变量,如果它们在使用前没有被明确赋值,编译器会报错。因此,如果你将一个变量result初始化为null,但随后又在代码中给它赋予了另一个非null的值,...
Variable initializer is redundant when the variable is already initialized with a value. For example, if we have a variable x with an initial value of 0, then the statement x = 0 is redundant. In programming, a variable initializer is a statement that assigns a value to a variable. It ...
Variable Initializer is Redundant in WebStorm In the world of coding and software development, WebStorm stands as a powerful integrated development environment (IDE) for JavaScript and other related technologies. It's renowned for its intelligent coding assistance, robust debugging capabilities, and seam...
However, most of the// time, we will immediately set sizes to {0} and reset numel to 0.// (Can't do that in the default initializers, because there's no way to// spell "allocate a one-element array" for strides_).int64_tnumel_=1;// INVARIANT: When storage is non-null, this ...
The initializer in the declaration is required; it identifies the object for which j is an alias. Moreover it is not possible later to change the object to which j refers; it will always refer to i. Any change to i or j can be seen by reading the other. Most C++ compilers implement...
initialization code to the constructor. Also, all the code in the instance initializers is moved to class constructors, in the order that they appear in the class. This explains why IntelliJ IDEA moves the extracted variable from a field initializer to an instance initializer, as demonstrated ...
So that the variable can be assigned a value later whose type isn't a subtype of the initializer's type. So seeing the type annotation on the local sends a useful signal of "hey this is going to be mutated later to a different type". ...
If you don’t provide any initialization data, or you provide null, the compiler has no information with which to infer the type, so the noInitializer and aNull types can’t be inferred. inferReturnType() is not allowed, even though it seems like the compiler has enough information to ...

I have a bunch of variable initializer is redundant warnings. I can't find anything about what it exactly means in terms of what I need to fix. Example: function calcPayNow(){ var payNowVal = 0; --snip--- payNowVal = (Math.round(tec * x) - Math.round(allpmts * x)) / x; -...
