operators found in Java

Slide2

Jumps

A jump is also known as a branch

A jump is when you program skips certain steps to move on to another block of code

There are two types of jumps

Unconditional Jump = no condition is set

Conditional jump = a condition has to be satisfied in order for the jump to compare Slide3

Logical Operators

Logical operators are functions used in Java

They are used to set certain conditions

These conditions are used when we have conditional jumps in our programs Slide4

Different Logical Operators

There are many different operators, some of these include the following

Logical Operator

Meaning

&

Logical

AND – both must

be true

|

Logical

OR – One or both must be true

^

Logical

XOR – the

NOT of the OR operator

||

Short Circuit

OR – this stops

when it finds the first true

&&

Short Circuit

AND – this stops

when it finds the first true

!

Logical Unary

NOT – true becomes false

and vice versa Slide5

Rational Operators

Rational operators in java are used when we wish to make a comparison

Rational operators just like logical operators are used for conditional jumps in our java program s Slide6

Different Logical Operators

Relational Operators

Meaning

==

Equal To

>

Greater Than

<

Less Than

>=

Greater Than or Equal To

<=

Less Than or Equal To

!=

Not Equal ToSlide7

Is the answer to these conditions true of false?

9 + 4 == 13

5*

5

> 10

10 – 4 < 5

15 >= (10+5)

21 / 7 <= 4

12*2 != 24Slide8

Is the answer to these conditions true of false?

9 + 4 == 13



False

5*

5

> 10

 True

10 – 4 < 5

 True

15 >= (10+9)

 False

21 / 7 <= 4

 True

12*2 != 24

 False
