Question 184
|
What is the output of the following JAVA program ?
class simple
{
public static void main(String[ ] args)
{
simple obj = new simple( );
obj.start( );
}
void start( )
{
long [ ] P= {3, 4, 5};
long [ ] Q= method (P);
System.out.print (P[0] + P[1] + P[2]+”:”);
System.out.print (Q[0] + Q[1] + Q[2]);
}
long [ ] method (long [ ] R)
{
R [1]=7; return R;
}
} //end of class
class simple
{
public static void main(String[ ] args)
{
simple obj = new simple( );
obj.start( );
}
void start( )
{
long [ ] P= {3, 4, 5};
long [ ] Q= method (P);
System.out.print (P[0] + P[1] + P[2]+”:”);
System.out.print (Q[0] + Q[1] + Q[2]);
}
long [ ] method (long [ ] R)
{

Question 184 Explanation:
First we will create the object of simple class.
By using object , we call the function start().
In the start() function definition, first statement is integer array with three elements.
long [ ] Q= method (P); Again function method(p) will be called.
In the definition of method function, we are changing the second element of array to value 7 and returning updated array to array Q.
We are passing address of P as argument to method so Modifications happened in the method automatically reflects to array P.
Both array P and Q consists of values {3,7,5}
The sum of the three values are 15
