1. MSME TDC –PPDC AGRA

2. JAVA

3. Object Oriented Programming Concepts Operators in Java Our Timeline Input in java Some concepts of objects and classes Values and Data Types Library Methods Iterative Construct

4. Elements of OOPS OBJECTS CLASS ENCAPSULATION ABSTRACTION POLYMORPHISM INHERITANCE

5. JAVA COMPILATION COMPILER A compiler is a program that translate code written in high level language into machine code in one go

6. JAVA COMPILATION Interpreter A interpreter is a program that translate code written in high level language into machine code line by line .

7. Normal Compilation In normal compilation the source code is directly converted to machine code .

8. JAVA COMPILATION IN Java compilation the source code is first converted to an intermediate code .i.e., the java byte code , which in turn is converted to machine code .

9. Layout shows the steps involved from Java program to final execution :

10. Package A package is named collection of java classes that are grouped on the basis of their functionality . The import keyword is used to load a package into java program . Syntax : import java .io.*;

11. Values and data types Character set It’s a set of all the letters of the English alphabet , digits, and some special characters that are valid in the java lang. The java characters set consist of the following : Letters Digits Special characters or delimiters : ! , #,$,%,^,&,*,(), etc . Operators There are two standard character sets ASCII and UNICODE , that are commonly used in java .

12. ASCII CODES

13. UNICODE

14. TOKENS

15. Keywords

16. Identifiers

17. literals

18. Operators

19. Punctuators and Separators Punctuators : These are the punctuation sign used in java programs . Separators : These are used to separate the variables or the characters.

20. Variables They are just a containers for storing data value. Syntax: <data-type> <variable-name>; int emp_age;

21. Types of variables

22. Library methods in java

23. Conditional construct in java

24. Decision making statements

25. Working of If’s statement

26. Flow chart

27. Output

28. Java if-else-if ladder

29. The switch statement is a multiway branch statement. It provides an easy way to dispatch execution to different parts of code based on the value of the expression.  Switch statement

30. Iterative constructs in java

31. While loop

32.  do-while loop is an Exit control loop. Therefore, unlike  for  or  while  loop, a do-while check for the condition after executing the statements of the loop body. Do –while loop

33. Special loops 1.Infinite loop: it’s a sequence of instruction in a computer program that repeats endlessly .This can happen due to any many reasons : Loop has no terminating condition Loop has a condition that can never be met. Loop has a condition that causes the loop to start over . 2. Null loop : It’s a loop that doesn’t contain any statement within itself .It can be used as a delay counter in which the loop executes for a predefined number of times .It does not have a loop body .
