java loops

1for(int i = 0; i < 10; i++)
2{
3  //do something
4  
5  //NOTE: the integer name does not need to be i, and the loop
6  //doesn't need to start at 0. In addition, the 10 can be replaced
7  //with any value. In this case, the loop will run 10 times.
8  //Finally, the incrementation of i can be any value, in this case,
9  //i increments by one. To increment by 2, for example, you would
10  //use "i += 2", or "i = i+2"
11}

1// Starting on 0:
2for(int i = 0; i < 5; i++) {
3  System.out.println(i + 1);
4}
5
6// Starting on 1:
7for(int i = 1; i <= 5; i++) {
8  System.out.println(i);
9}
10
11
12// Both for loops will iterate 5 times,
13// printing the numbers 1 - 5.

1String[] cars = {"Volvo", "BMW", "Ford", "Mazda"};
2for (String i : cars) {
3  System.out.println(i);
4}

1int values[] = {1,2,3,4};
2for(int i = 0; i < values.length; i++)
3{
4 	System.out.println(values[i]); 
5}

1//Main two types of loops:
2//For loop:
3for(/*index declaration*/int i=0; /*runs as long as this is true*/
4   i<=5; /*change number at end of loop*/i++){
5doStuff();
6
7}
8//While loop:
9//runs as long as the condition is true
10while(condition){
11//do what you want in here
12doStuff()
13}

1//This will do the look 4 times
2for(int i = 0; i < 4; i++)
3{
4  ...
5  }
