Declaring Variables

Declaring Variables
In this example, a String object is declared and initialized with a reference to the 
String "blah" at the top of the main() method. An int named k is declared after the 
String object but is not given a value until later in the program. Another int named 
j is declared and intialized in the for loop. This variable will not be accessible 
outside of the for loop.
public class TestDeclare {
  public static void main(String args[]) {
    String str = "blah";
    int k;
    k = 2;
    for (int j = 0; j < 2; ++j) {
      System.out.println("j is " + j);
