CS1S Homework 2 -- Due Sept. 29, 2005

Name:___________________________

1) Write the declaration for an array of floating point numbers:

2) Create an array of three booleans, and set all three elements to 'true'.

3) Each of 5 students took 3 different tests: math, verbal, and composition. Create a matrix (an array of arrays) in which to store these scores as doubles. Each row will represent a student, and each column will represent a test. (I expect only 1 line of code.)

4) Describe the variable 'args' in the following line of Java code:

public static void main( String args[] ) {

5) When the size of an array is not known until run time, how can a program calculate the boundary value of a 'for' loop which must operate on each element of the array?
