Java(2)---LEARN JAVA: VARIABLES

LEARN JAVA: VARIABLES

What this lesson is about...

Introduce these built-in types and more: 

   types of these variables are int, double, and boolean

• ints hold positive numbers, negative numbers, and zero. They do not store fractions or numbers with decimals in them. (Declares a variable)

• To declare a variable of type double, The double primitive data type can help. double can hold decimals as well as very large and very small numbers.
• boolean values help navigate decisions in our programs. Answered with a boolean, a type that references one of two values: true or false.
• The char data type can hold any character, like a letter, space, or punctuation mark.

Expected Grades:

The char data type can hold any character, like a letter, space, or punctuation mark.

• use Strings, which are objects, instead of primitives. Strings hold sequences of characters

What I learned in this lesson...

clearspan style="font-size: large;">NOTES: The differences between the Integer and String objects in Java are: Integer can be converted to String, but String cannot be converted to Integer. Integer is a numeric value and String is a character value represented in quotes.

What I'm doing tomorrow...

I will be moving onto the next lesson which is LEARN JAVA: MANIPULATING VARIABLES
