Steps for learning Java programming are:

1.Familiarize yourself with the basics of programming concepts such as data types, control structures, loops, arrays, and functions.

2.Set up a development environment: Install the Java Development Kit (JDK) and a text editor or Integrated Development Environment (IDE) like Eclipse or IntelliJ IDEA.

3.Start with Java basics: Learn the syntax, data types, and control structures in Java. Practice writing basic programs to get a feel for the language.

4.Learn Object-Oriented Programming (OOP): Java is an object-oriented programming language, so it's important to understand OOP concepts such as classes, objects, inheritance, and polymorphism.

5.Learn the Java API: Java provides a rich set of built-in libraries, known as the Java API. Familiarize yourself with the Java API classes and how to use them in your programs.

6.Practice writing programs: Write programs that use the concepts you have learned so far, such as loops, arrays, functions, and OOP concepts.

7.Learn Advanced Java topics: Once you have a solid understanding of the basics, you can move on to more advanced topics like multithreading, database programming, and web development using Java.

8.Participate in online communities and forums: Join online forums and communities to ask questions, learn from others, and share your knowledge.

9.Practice, practice, practice: The more you practice, the better you will become at programming in Java. Set yourself coding challenges and work on projects to keep improving.

10.Stay up-to-date with Java developments: Java is an evolving language, so it's important to stay up-to-date with the latest developments and best practices. Read Java blogs and attend online or in-person events to stay current.

                           Here is a brief cheat sheet for Java:

1.Variables: declared with a type (e.g. int, float, double, char, etc.) and must be initialized before use.

2.Basic data types: int, double, float, char, boolean.

3.Arrays: declared with a type and size, e.g. int[] arr = new int[10].

4.Loops: for, while, do-while.

5.Conditional statements: if-else, switch.

6.Classes: blueprint for objects, with variables (fields) and methods (functions).

7.Objects: instances of a class, created with the new keyword.

8.Constructors: special methods called when an object is created, used to initialize fields.

9.Inheritance: allows classes to inherit fields and methods from a parent class.

10.Polymorphism: ability of objects to take on multiple forms, e.g. a parent class reference can refer to a child class object.
