Description
A local variable of a method or constructor has been found to have no writes to it.
This will cause a compile error when the project is built.
Java always expects a local variable to be assigned a value before it is read from. If no assignment is performed, Java will raise a compile error indicating that the variable was expected to be initialized before use.
Bad Practice
In the example below, x is not written to before use.
int someMethod() {
int x;
// x is never written to.
return x + 5; // will cause a compiler error.
}
Recommended
Always initialize variables to a sensible default value before using them.
int someMethod() {
int x = 0;
return x + 5;
}
