pls solve fast.I have a exam tomorrow​

Answer 1

Answer:

methods name

Return value

void main

local variable boolean answer,num1,num2

output=true

Answer 2

$\large{ \underbrace{ \underline{ \sf{C ode:-}}}}$

class Value_returned_by_function

{

boolean returnValue( int num1, int num2 )

{

if(num1<num2)

return true;

else

return false;

}

public void main()

{

boolean answer;

answer = returnValue (300,800);

System.out.println("The value returned is "+answer);

}

}

a) Write the names of the method present in this class.

• There are two methods in this class. One is parameterized ( having parameter(s) ) and another non-parameterized ( not having parameter(s) ). They are:-

1. returnValue( int num1, int num2 )
2. main()

b) Name the local variable used in this class.

• The variable used within a method (here, main() method) are called local variables.
• Here only 1 variable is used i.e. "answer" .

c) What is the output if main() is executed.

• The output is...

$\underline{ \orange{ \tt{The \: value \: returned \: is \: true}}}$

Explanation:-

• When function main() is executed, a variable answer of type boolean is declared.
• When the control moves further, it executes " answer = returnValue (300,800) " and here a function returnValue () is called by passing the values 300 and 800 respectively to num1 and num2.
• Now let's proceed to returnValue ().
• Note the parameters, num1 is initialised to 300 and num2 is initialised to 800.
• A condition is checked, is num1<num2? that is is 300<800?
• Yes, 300 is less than 800, first statement is executed which returns true to the main().
• Once the value is returned to caller program, variable answer gets the Boolean value true .
• And finally, the result is printed,

The value returned is true
