To add 0.01 + 0.02 + ... + 1.00, what order should you use to add the numbers to get better accuracy?

add 0.01, 0.02, ..., 1.00 in this order to a sum variable whose initial value is 0.

add 1.00, 0.99, 0.98, ..., 0.02, 0.01 in this order to a sum variable whose initial value is 0.

Analyze the following code: public class Test { public static void main(String[] args) { System.out.println(xMethod(5, 500L)); } public static int xMethod(int n, long l) { System.out.println("int, long"); return n; } public static long xMethod(long n, long l) { System.out.println("long, long"); return n; } }

The program displays int, long followed by 5.

The program displays long, long followed by 5.

The program runs fine but displays things other than 5.

The program does not compile because the compiler cannot distinguish which xmethod to invoke.

__________ is to implement one method in the structure chart at a time from the top to the bottom.

Bottom-up and top-down approach

Which of the following should be defined as a void method?

Write a method that prints integers from 1 to 100.

Write a method that returns a random integer from 1 to 100.

Write a method that checks whether a number is from 1 to 100.

Write a method that converts an uppercase letter to lowercase.

What is k after the following block executes? { int k = 2; nPrint("A message", k); } System.out.println(k);

k is not defined outside the block. So, the program has a compile error

All Java applications must have a method __________.

public static void main(String[] args)

public static Main(String[] args)

public static Main(String args[])

public void main(String[] args)

public static main(String[] args)

__________ is a simple but incomplete version of a method.

A method developed using top-down approach

The signature of a method consists of ____________.

return type, method name, and parameter list

The __________ method copies the sourceArray to the targetArray.

System.arraycopy(sourceArray, 0, targetArray, 0, sourceArray.length);

System.copyArrays(sourceArray, 0, targetArray, 0, sourceArray.length);

System.copyarrays(sourceArray, 0, targetArray, 0, sourceArray.length);

System.arrayCopy(sourceArray, 0, targetArray, 0, sourceArray.length);

What is output of the following code: public class Test { public static void main(String[] args) { int[] x = {120, 200, 016}; for (int i = 0; i < x.length; i++) System.out.print(x[i] + " "); } }

016 is a compile error. It should be written as 16.
