# More Midterm Review
|
|
|
|
Let us suppose that we have the following array
|
|
|
|
```java
|
|
int[] b = {11, 12, 15, 16, 21}
|
|
```
|
|
|
|
## Increase all elements by 2
|
|
|
|
```java
|
|
for (int i = 0; i < b.length; i++) {
|
|
b[i] += 2;
|
|
}
|
|
```
|
|
|
|
## Print all elements of array
|
|
|
|
```java
|
|
for (int i = 0; i < b.length; i++) {
|
|
System.out.println(b[i]);
|
|
}
|
|
```
|
|
|
|
## Sum all the elements of an array
|
|
|
|
```java
|
|
int sum = 0;
|
|
for (int i = 0; i < b.length; i++) {
|
|
sum += b[i];
|
|
}
|
|
```
|
|
|
|
## Access Last Element of Array
|
|
|
|
```java
|
|
System.out.println(b[b.length - 1]);
|
|
```
|
|
|
|
## Access the middle element
|
|
|
|
```java
|
|
System.out.println(b[b.length / 2]);
|
|
```
