Back to Question 24

Answer 23

The following three logical or conditional operators are supported by Java.

The logical or conditional operators Operator Typical Use Returns true if&&Left&&Right Left and Right are both true || Left || Right Either Left or Right is true! ! Right Right is false

Answer 22

This program produces the following output:

The relational 6<5 is false The relational 6>5 is true

Back to Question 22

Answer 21

Java supports the following set of relational operators:

Relational operators Operator Returns true if>Left operand is greater than right operand>= Left operand is greater than or equal to right operand<Left operand is less than right operand<= Left operand is less than or equal to right operand== Left operand is equal to right operand != Left operand is not equal to right operand

Back to Question 21

Answer 20

Relational operators return the boolean type in Java.

Answer 19

Java supports the following four unary arithmetic operators.

Unary arithmetic operators Operator Description + Indicates a positive value- Negates, or changes algebraic sign ++ Adds one to the operand,both prefix and postfix -- Subtracts one from operand,both prefix and postfix

Back to Question 19

Answer 18

The operator coerces the value of the right operand to a string representation for use in the expression only. If the right operand is avariable, the value stored in the variable is not modified in any way.

Back to Question 18

Answer 17

The plus operator (+) is also used to concatenate strings as in the following code fragment:

String concatenation "MyVariable has a value of " + MyVariable + " in this program."

Back to Question 17

Answer 16

Java support various arithmetic operators on floating point and integer numbers. The following table lists five of the binary arithmetic operators supported by Java.

Binary arithmetic operators Operator Description+ Adds its operands - Subtracts the right operand from the leftoperand * Multiplies the operands/ Divides the left operand by the right operand% Remainder of dividing the left operand by the right operand

Back to Question 16

Answer 15

As a result of performing the specified action, an operator can be said to return a value (or evaluate to a value) of a given type. The type depends on the operator and the type of the operands. To evaluate to a value means that after the action is performed, the operator and its operands areeffectively replaced in the expression by the value that is returned.

Back to Question 15

Answer 14

False: Binary operators use infix notation, which means that the operator appears between its operands.

Back to Question 14

Answer 13

The output from this Java application follows:

  • x = 5
  • X = 5
  • x + X++ = 10
  • X = 6
  • y = 5
  • Y = 5
  • y + ++Y = 11
  • Y = 6

fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
