Method: Java statements are grouped together in methods. Each method must be inside a class. Every method has a name, which starts with a lowercase character.You can identify a method name because it is always followed by left and right parentheses, which may enclose arguments (parameters).

Example:

public void hello(String name){
System.out.println("Hello "+ name);
}

Here hello() is method.

Variables: A variable refers to the memory location that holds values like: numbers, texts etc. in the computer memory. A variable is a name of location where the data is stored when a program executes.

Example:

boolean value=true;
int i=5;

Here variables are value and i respectively.

datatype: The type of value that a variable can hold is called data type.

Example:

boolean value=true;
int i=5;

Here boolean and int are datatype.

Object: An object is a runtime entity which is created by a class. It is a software bundle of variables and related methods.

Example:

Integer ig=new Integer();

Here ig is an object

Attribute: An instance or static variable, usually called a field.

Example:

Integer ig=new Integer(Integer.SIZE);

Here SIZE is an attribute
