I want an explanation as to why the first program doesn't recognize the variable smaller, and why you must initialize the variable outside of the if statement, as shown in the second program

First Program:

Second Program:

Type your solution here: Dublic class Oops4 \{ public static void main(String[] args) \{ int a =7,b=42; int smaller = minimum(a, b); if(smaller ==a ) \{ System. out.println("a is the smallest!"); \} public static int minimum(int a, int b) \{ int smaller; if(a=a; \} else \{ smaller =b; \} return smaller
