Loops ; Java

Loops are structures that are run repeatedly according to the instructions or conditions.
There are two types of loops in Java: a while loop and a for loop, both are written differently.

An example of a while-loop and a for-loop that prints 1 through 10

Conditions

A for-loop uses the syntax of for(int *var_name* = *value* ; *var_name with condition*; *change value of var_name*)
A while loop uses the syntax of while(*condition*) but the variable(s) must be created before the loop.

Syntax ; Writing

Here is the list:

• int __ = ___;
• String __ = ___;
• boolean __ = ___;
• ArrayList <__> __ = new ArrayList <__> ;
• A class must have the first letter at an uppercase
• Name of the java file must match with the class name
• If a variable is written with more than one word - write it as uppercase of the first letter of the second word (ex:myName)
• Writing a for loop with a condition that exceeds the limit of a value or length will result an OutOfBounds exception
• Write the variable type correctly - variables like int or boolean are not uppercase(unless you are creating an ArrayList).

public class Main{
*indent* public static void main(String[] args){
*indent* }
}
