Local type variable inference is the formal name of “var” in Java. From the name, you might deduce some things about allowed or disallowed locations. For example, a local variable in a method is allowed and an instance variable declaration is not.

Scopes that are even more granular are also allowed such as inside a for loop or try with resources statement.

I learned today that instance and static initializers are allowed as well.

public class LVTI {
public int myValue;
{
var temp = 3;
myValue = temp;
}
}
}

In hindsight, this makes sense. An initializer is a block of code. Which can have local variables.
