Consider the following code segment.
boolean a = true;
boolean b = false;
System. out. print((a == !b) != false);
What is printed as a result of executing this code segment?
false
true
0
1
Nothing is printed because the expression (a == !b) != false is an invalid parameter to the System. out. print method.
The following code segment prints one or more characters based on the values of boolean variables b1 and b2. Assume that b1 and b2 have been properly declared and initialized.
if (!b1 || b2)
{
System. out. print("A");
}
else
{
System. out. print("B");
}
if (!(b1 || b2))
{
System. out. print("C");
}
else
{
System. out. print("D");
}
if (b1 && !b1)
{
System. out. print("E");
}
If b1 and b2 are both initialized to true, what is printed when the code segment has finished executing?
ABCD
ABD
AD
BD
BDE
Consider the following code segment.
String str1 = new String("Happy");
String str2 = new String("Happy");
System. out. print(str1.equals(str2) + " ");
System. out. print(str2.equals(str1) + " ");
System. out. print(str1 == str2);
What is printed as a result of executing the code segment?
true true true
true true false
false true false
false false true
false false false
Consider the following two code segments. Assume that variables x and y have been declared as int variables and have been assigned integer values.
I.
int result = 0;
if (x > y)
{
result = x - y;
System. out. print(result);
}
else if (x < y)
{
result = y - x;
System. out. print(result);
}
else
{
System. out. print(result);
}
II.
if (x < y)
{
System. out. print(y - x);
}
else
{
System. out. print(x - y);
}
