Create Flow Charts for the following Java LOOP statements

int i; // counter variable
for( i = 1; i <= 100; i = i + i )
System.out.println( "i is now: " + i );
___________________________________________
int num = 10;
while( num > 1 )
{
System.out.println( “num is: ” + num );
num = num / 2;
}

______________________________________________
int num = 10;
do
{
num = num /2 ;
System.out.println( “num is: ” + num );
}while( num > 1 );

Write  for  statements (loop)  that will print out the

• numerals 1,2,3,4
• numerals 2,4,6,8 

This is a graded assignment

1.  Look at the source code for Final.java.   The nested if statements can be replaced in just one statement using comparison and conditional operators.   Write the statement.     Look at p. 599 in book

2.  Run Deposit.java    What are the results when  depositAmount is
$1000
$900
$2000
$50

Project 6.1   p. 606
Given the variables in a Java Program
int  i = 4;
int  j = 3;
boolean true_false;

Evaluate the following
true_false = (  j <4);
true_false = (  j < 3);
true_false = (  j < i );
true_false = ( i < 4 );
true_false = ( j != i );
true_false = (j == i   ||   i < 100)
true_false = (j == i  &&  i < 100)
true_false =  !(j <4)
true_false =  !true
