1. LOOPS
BY: LAUREN & ROMEO

2. There are 3 types of loops:
A loop allows you to execute a group of statements as many times as needed
There are 3 types of loops: 1 2 3
Do-While
While
For

3. Do-while
A loop that executes statements before checking the Boolean expression in the while statement.
Always loops at least once
EXAMPLE:
Number is declared as 0
int number=0;
do{
number+=1;
}while(number<=10)
1 is added to the variable: number every time loop initiates
CONDITION: loop initiates when the number is below or equal to 10.

4. while
A while statement is a loop that checks the Boolean expression before executing the statements within the loop.
Does not always loop once
EXAMPLE:
Number is declared as 0
int number=0;
while(number<10) {
number+=1; }
1 is added to the variable: number every time loop initiates
CONDITION: loop initiates only when the number is below 10.

5. for
A for statement is a counter loop that counts the number of times the statements in the loop are iterated
EXAMPLE:
Int i is declared as 0
Loop initiates when i is below or equal to 10
For (int i=0;i<=10;i++){
System.out.println(“Hello”); }
1 is added to i every time loop iterates
Loop displays the phrase “hello” every time

6. Nested Loop EXAMPLE: A nested loop is a loop within a loop
for loop will iterate 10 times
int num = 0;
for (int i=0;i<=10;i++){
do{
num+=1;
System.out.println(“Hello”);
}while(num==i); }
1 is added to the variable: num every time loop iterates
CONDITION: do-while loop will stop iterating when num is equal to i

7. Infinite Loops EXAMPLE: int number = 0; do { number += 1;
An infinite loop is a loop that contains an error to make it iterate infinite times because the condition is never met
EXAMPLE:
Number is declared as 0
int number = 0;
do {
number += 1;
} while (number >0);
1 is added to the variable: number every time the loop iterates
CONDITION: loop initiates when the number is greater than 0.
