                            primaryWeapon = MTAR; //*&%&*This is where i initialized it.
    }
                return; 

                            }
    System.out.println("Primary Weapon: " + primaryWeapon); //This is where the error is. It say's im not initializing the variable but I initialize it in the last if statement
    }
    }
    }

Answer 1

It say's im not initializing the variable but I initialize it in the last if statement

如果不执行“if” block 会发生什么？那么该变量将被取消分配，对吧？这就是编译器提示的原因。

局部变量应该在所有可能的流程中赋值，否则会出现编译时错误。
