- What is the output of this program?
public class Output
{
public static void main(String args[])
{
double num0 = 5.0;
double num1 = 2.0;
double num2 = Math.pow( num0, num1 );
System.out.print(num2);
}
}

NA
Correct Option: D
Math.pow(num0, num1) methods returns value of num1 to the power num0, i:e num0 ^ num1, 5.0 ^ 2.0 = 25.0
- What is the output of this program?
public class Result
{
public static void main(String args[])
{
double num0 = 4.15;
double num1 = 5.16;
double num2 = Math.max( num0, num1 );
System.out.print(num2);
}
}

- What is the output of this program?
public class Result
{
public static void main(String args[])
{
byte array0[] = { 71, 72, 73, 74, 75, 76 };
byte array1[] = { 77, 78, 79, 80, 81, 82 };
System.arraycopy(array0 , 1, array1, 3, 0);
System.out.print(new String(array0) + " " + new String(array1));
}

NA
Correct Option: C
Since last parameter of System.arraycopy(array0, 1, array1, 3, 0) is 0 nothing is copied from array a to array b, hence b remains as it is.
