Introduction to Java
Java is a class-based, object-oriented programming
for simplicity and portability. The core principle, wr
anywhere WORA, allows compiled Java code to exe
with a Java Virtual Machine JVM without recompil
portability, coupled with robustness and security, m
choice, even when preparing for Data Structures Alg
interviews for major tech companies.
However, Java isnt purely object-oriented. Wh
into the paradigm, primitive data types like in
objects themselves, and the static keyword allo
members without object instantiation concept
from pure OO principles. Java provides wrapp
Integer and Float to represent primitives as ob
needed.
