Question

Refer to the code segment below and answer the questions in the comments labelled Question i – vi. For each answer; provide a brief explanation for your answer.

public class Scope {

private int x = 2;

private int x = 1;

public void start() {

int x = 5;

int x = 2;

//Question i

System.out.printf( "The value of x is %d\n", x );

int x = 2;

//Question ii

System.out.printf( "\nThe value of x is is %d\n", x );

} // end method begin

public void middle() {

int x = 25;

//Question iii

System.out.printf( "\nThe value of x is %d\n", x );

++x;

//Question iv

System.out.printf( "The value of x is %d\n", x );

} // end method middle

public void end(){

//Question v

System.out.printf( "\nThe value of x is %d\n", x );

x *= 10;

//Question vi

System.out.printf( "The value of x is %d\n", x );

} // end method end

} // end class Scope

Answer 1

Question i

It will be printed:"The value of x is 2" // last value of x before the given command System.out.printf

Question ii

It will be printed:"The value of x is 2" // last value of x before the given command System.out.printf

Question iii

It will be printed:"The value of x is 25" // the value of x in the given method

Question iv

It will be printed:"The value of x is 26" // the value of x after increment ++x

Question v

It will be printed:"The value of x is 1" // the method takes the value of x which is defined in class Scope (private x=1)

Question vi

It will be printed:"The value of x is 10" // x=1*10=10
