  1. (Java Programming: 42% total and 07% each) What is the output of each of the following programs? The answer is ERROR if the program contains syntactic Gavac) errors or semantic Gava) errors public class o public static void main(string 1 anys) myStaticMethod : 01 mb) = new 012); myObj.my PublicMethod ); 3 static void myStatic Method System.out.print “Statle): public void my publicMethod) System.out.print Public) 1 > \/\/ Output: 11 public class 02 public static void maini Stringargs) Increment demol – new Increment Increment demo2 = new Calculation (): System.out.printi demol.incl 3 ) ); System.out.printi demo2.Inc2 1 4)); class Increment public int incl( int x) return( x + 1) 7 class Calculation extends Increment public int incat int x) return { super.incl\/ *+1 ) : 2 \/\/ Output:<\/li>\n<\/ol>\n\n\n\n

    The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n

    Let’s break down both programs you provided and analyze them carefully to determine their output and possible errors.<\/p>\n\n\n\n

    First Program (Java):<\/strong><\/h3>\n\n\n\n
    public class Main {\n    public static void main(String[] args) {\n        myStaticMethod(); \/\/ Calling static method\n        MyClass myObj = new MyClass();\n        myObj.myPublicMethod(); \/\/ Calling non-static method\n    }\n\n    static void myStaticMethod() {\n        System.out.print(\"Static\");\n    }\n\n    public void myPublicMethod() {\n        System.out.print(\"Public\");\n    }\n}\n<\/code><\/pre>\n\n\n\n
    Analysis:<\/strong><\/p>\n\n\n\n
      \n
    • Static Method:<\/strong> The method myStaticMethod<\/code> is called inside the main<\/code> method. Since it is static, it can be accessed directly using the method name myStaticMethod()<\/code>.<\/li>\n\n\n\n
    • Non-static Method:<\/strong> myPublicMethod<\/code> is a non-static method, and it is called through an instance of the MyClass<\/code> class (myObj<\/code>), which is created using MyClass myObj = new MyClass();<\/code>.<\/li>\n<\/ul>\n\n\n\n
      Output:<\/strong> The program should print StaticPublic<\/code> because:<\/p>\n\n\n\n
        \n
      • myStaticMethod()<\/code> prints \"Static\"<\/code>.<\/li>\n\n\n\n
      • myPublicMethod()<\/code> prints \"Public\"<\/code>.<\/li>\n<\/ul>\n\n\n\n
        Thus, the output for this program is:<\/p>\n\n\n\n
        StaticPublic\n<\/code><\/pre>\n\n\n\n
        Second Program (Java):<\/strong><\/h3>\n\n\n\n
        public class Main {\n    public static void main(String[] args) {\n        Increment demo1 = new Increment();\n        Increment demo2 = new Calculation();\n        System.out.print(demo1.incl(3));  \/\/ Output from demo1\n        System.out.print(demo2.incl(4));  \/\/ Output from demo2\n    }\n}\n\nclass Increment {\n    public int incl(int x) {\n        return x + 1;\n    }\n}\n\nclass Calculation extends Increment {\n    public int incl(int x) {\n        return super.incl(x) + 1;  \/\/ Calling the base class's incl method\n    }\n}\n<\/code><\/pre>\n\n\n\n
        Analysis:<\/strong><\/p>\n\n\n\n
          \n
        • Class Increment<\/code>:<\/strong> It has a method incl(int x)<\/code> which simply returns x + 1<\/code>.<\/li>\n\n\n\n
        • Class Calculation<\/code>:<\/strong> It extends Increment<\/code> and overrides the incl(int x)<\/code> method. This method calls super.incl(x)<\/code> to invoke the incl<\/code> method from the parent class (Increment<\/code>), and then adds 1 to the result.<\/li>\n<\/ul>\n\n\n\n
          Execution Flow:<\/strong><\/p>\n\n\n\n
            \n
          • When demo1.incl(3)<\/code> is called, it uses the incl<\/code> method from the Increment<\/code> class, so the result is 3 + 1 = 4<\/code>.<\/li>\n\n\n\n
          • When demo2.incl(4)<\/code> is called, it uses the overridden incl<\/code> method from the Calculation<\/code> class. First, it calls super.incl(4)<\/code> (which calls incl<\/code> from Increment<\/code>, returning 4 + 1 = 5<\/code>), and then adds 1 to the result, giving 5 + 1 = 6<\/code>.<\/li>\n<\/ul>\n\n\n\n
            Output:<\/strong> The program will print 46<\/code> because:<\/p>\n\n\n\n
              \n
            • demo1.incl(3)<\/code> prints 4<\/code>.<\/li>\n\n\n\n
            • demo2.incl(4)<\/code> prints 6<\/code>.<\/li>\n<\/ul>\n\n\n\n
              Thus, the output for this program is:<\/p>\n\n\n\n
              46\n<\/code><\/pre>\n\n\n\n
              Summary of Output:<\/strong><\/h3>\n\n\n\n
                \n
              • First Program:<\/strong> StaticPublic<\/code><\/li>\n\n\n\n
              • Second Program:<\/strong> 46<\/code><\/li>\n<\/ul>\n\n\n\n
                Both of the programs are syntactically correct and free of semantic errors. The first program demonstrates the use of static and non-static methods, while the second program demonstrates method overriding and calling methods from the superclass.<\/p>\n","protected":false},"excerpt":{"rendered":"
