Question

1. USING YOUR KNOWLEDGE OF MODULES, REWRITE THE FOLLOWING BATCH OF CODE USING PSEUDOCODE AND CREATE A FLOWCHART TO REPRESENT THE LOGIC:

There’s one thing every coder must understand.

The System.out.println command.

There’s one thing every coder must understand.

The System.out.println command.

Answer 1

Ans:- For understanding this, Consider following code:

public class System{

public static final PrintStream out;

.......

}

public class PrintStream{

public void println(){

}

public void println(String s){

}

-----------

many overloaded method

}

Now if we want to use method println() then how it should be called

System.out.println() //depends on its argument

System ->class in java.lang package

out -> PrintStream object reference which is static variable of System class, so access through( System.out)

println() -> Method in PrintStream class which is accessed by out(object reference variable) (System.out.println())

Pseudocode for System.out.println()

Class System

BEGIN

Declare variable for PrintStream as out

Implement other method of class

END

class PrintStream

BEGIN

implement method println()

implement method println(String s)

implement method println(String,operator,other type variable)

---------------------

other overloaded method

END

class Test

Begin

main()

begin

System.out.println("Hello World")// calling method println()

end

END

Flowchart
