For() - Basic Programming Concepts With psudo Code

for is an looping statement.it used to execute the tast until reach the condition. syntax for(installation,condition,increment or decrement) { //statements or block of code. } example, main() { int i; for(i=1;i<=10;i++) { printf("\n %d",i); } }

Class is a collection of similar objects. Which have common properties

Class is a collection of similar objects. Which have common properties. Syntax class class_name { //member functions and variables. } How to create a objects for class class_name c=new class_name; We can access the member variable and member methods using dot operator. c.member_function(); Eg : class bike { void fun() { System.out.println("member method"); } public static void main(String[] args) { bike B=new bike(); B.fun(); } } output member method
