Variables, Data Types, and Memory
Variables: a named storage location used to store data in a program.
Data Types:
Primitive: predefined data types provided by the language, such as int, char,
double, etc.
Non-primitive: reference types that refer to objects, such as arrays, strings, and
user-defined types.
Custom-defined: user-defined data types, such as classes and interfaces.
Loops
for loop: repeats a block of code a specific number of times.
while loop: repeats a block of code while a specific condition is true.
do-while loop: repeats a block of code at least once and then continues to repeat
while a specific condition is true.
Java Fundamentals and Output
Java fundamentals: understanding the basics of the Java programming language, such
as variables, data types, and loops.
Output: the process of displaying information in a program.
Conditioning and Decision Making
Conditional statements: determine the flow of a program based on certain
conditions.
if-else: executes a block of code if a specific condition is true, and another
block of code if the condition is false.
switch-case: executes a block of code based on a specific value.
Operators and Type Casting
Operators: symbols that perform operations on operands (variables or values).
Type casting: converting a value from one data type to another.
User Input and Scanner Class
User input: getting input from the user in a program.
Scanner class: used to get input from the user in Java.
Functions and Methods
Functions: reusable blocks of code that perform a specific task.
Methods: functions that are associated with an object of a specific class.
Arrays and Multidimensional Arrays
Arrays: a collection of elements of the same data type.
Multidimensional arrays: arrays with more than one dimension.
