DIn Java, the scope of a variable is defined by its block structure. The variable "u" declared within a block inside the method "funcOne" (Line 24) is not visible outside of its declaring block, making it not visible to the rest of the method "funcOne". The identifier "first" refers to a method name (Line 13), and method names are not considered "visible" in the context of variable scope within another method; instead, they are callable. The static variables "intRate" (Line 3) and "salary" (Line 17) are class-level variables, making them visible throughout the class, including within the method "funcOne".
