Using decisions

- Now that we've had a review of Data Types,…let's talk about adding decision-making logic in Java.…When adding decision-making logic in Java,…the programmer often uses Relational Operators…to compare two values,…such as, <, <=,…>, >=, ==,…which, remember, is two = signs, or !=.…Do you remember what the "not" symbol is?…It's the !, Shift + 1.…

In addition, sometimes it is necessary…to join two or more statements.…This can be done using Logical operators:…"and", which is two &,…and "or", which is two |.…Remember that the result of any comparison…is always a Boolean value, either true or false.…Here is another example program…with some decision-making logic added.…Let's take a look.…I start out with a println statement…that asks the user to enter their age.…

We read that value in, on line 14, and age = in.nextIn ( ).…Now, we use the Relational Operator <…to compare the value entered by the user…to determine the age grouping of this person.…If the age < 2, it's gonna print out "Infant",…else if the age < 12, it'll print out "Child".…
