## better way to find the list size once and limiting the scope of variables.

```java
  for( int i=0 , n=test.size();i<n;i++) {
            System.out.println(test.get(i));
        }
```


## After 1.5 java we can use for each 

```java
  for(int a : test) {
            System.out.println(a);
        }
```
