Question
I need help with the following assignment in Java.
Match the following terms to the definition below. Note that there are more terms than definitions.
*=
=*
**
(double)
<double>
(floating)
<floating>
0
1
block
box
counter-controlled
if
if…else
garbage
group
nested
post-fix
pre-fix
sentinel
sequence
set
strongly-typed
weakly-typed
Which term from the above word bank matches each description below?
This value can be used to terminate repetition when the number of iterations is not known in advance
Default value for instance variables of type int, bool, double
Use this type of loop when the number of iterations is known in advance
Statement is used to execute one action when a condition is true and another when that condition is false
Can use this compound operator toshorten: a = a * 2
A language that requires all variables to have a type
x++ is ____ increment
A control statement inside another control statement
Used to make a temporary floating-point copy of its operand
A set of statements contained in a set of { }’s
Answer the following questions:
Write 4 different ways to add 1 to the integer variable num
How many times does the following loop execute?
int i = 0;
while (i <= 2)
{
System.out.println("in the loop");
i++;
}
What does the following code output?
int i = 3;
if (i == 2);
System.out.println("in if");
System.out.println("after the if");
How many times does the following loop execute?
int x = 0;
int total = 0;
while (x < 5)
total += x;
x++;
Looking at the following code, what word do you think you should replace xxx with? yyy with?
if (num % 2 == 0)
System.out.prinln("num is xxx");
else
System.out.prinln("num is yyy");

______________________
Write 4 different ways to add 1 to the integer variable num
1) num++ ;
2) ++num ;
3) num=num+1;
4) num += 1;

How many times does the following loop execute?
int i = 0;
while (i <= 2)
{
System.out.println("in the loop");
i++;
}
Ans) 3 times (for i= 0 , 1 , 2)
_________________________
What does the following code output?
int i = 3;
if (i == 2);
System.out.println("in if");
System.out.println("after the if");
Ans)after the if
Reason: as the valu eof x =3 then the if block will not get executed .So the statement after the if block will be executed.
___________________________
How many times does the following loop execute?
int x = 0;
int total = 0;
while (x < 5)
total += x;
x++;
Ans) infinite times.
Reason: the value of x=0 every time the condition check 0<5 is true .But the value of x will never be incremented because x++ ; is outside the while loop.so this loop continues to execute for infinite times.

Looking at the following code, what word do you think you should replace xxx with? yyy with?
if (num % 2 == 0)
System.out.prinln("num is xxx");
else
System.out.prinln("num is yyy");
Ans)
xxx should be replaced with even
yyy should be replaced with odd.
