Why Java …..

JDK, JRE And IDE

• Java Development Kit

• Java Runtime Environment

• Integrated Development Environtment

Java Syntax

• Types:

Kinds of values that can be stored and manipulated:

• boolean: Truth value (true or false).

• int: Integer (0, 1, -47).

• double: Real number (3.14, 1.0, -2.1).

• String: Text (“hello”, “example”).

• Array: Array is and object of any of the previous data types

Form:Type name;

Type name = value ;

Array’s Form:

Type name[] = new Type[no. of elements];

Type name[] = {E,L,E,M,E,N,T,S}

Java Syntax

• Operators:

Symbols that perform simple computations

• Assignment: =

• Addition: +

• Subtraction: -

• Multiplication: *

• Division: /

• Remainder %

Note:

Dependency of the

Mathematical

computations is same as

that dependency of

Equations in Math.

x(t) = 0.5 × at2 + vit + xi

JAVA SYNTAX

Symbols that represents logical operations:

• ! not logical negation

• && and logical conjunction

• || or logical disjunction

**Usually used in If Statements

Java Syntax

Data input:

• First we build an OBJECT from the Class “Scanner”.

• Then we use this object to read the data input from the user.

Form:Scanner name = new Scanner (System.in);

Type name = name.nextType ;

Java Syntax

Data Output:

• Use the Form :

• Sentences needs to be in Quotations, Variables needn’t.

Form:System.out.print(“ sentence ” + variable);

Or

System.out.print(“ sentence ” + variable);
