Java Test 1

State the output from this program fragment:
```    int a = 5;
int b = 7;
a = a + b;
b = a + b;
```
State the output from this program fragment:
```    int a = 5;
int b = 7;
int c = 8;
a = b;
b = c;
c = a;
System.out.println(100*a+10*b+c)
```
State the output from this program fragment:
```    String s = "Fourty two";
String t = s.substring(7,8)+substring(1,4);
System.out.println(t);
```
The program fragment and the output are shown. State the missing value for q
Program Fragment ```for(int i=q; i<9; i+=3) System.out.print("x"); ``` xxxx

The program fragment and the output are shown. State the highest possible value for q.
Program Fragment for(int i=q; i<9; i+=3) ``` System.out.print("x"); ``` xxx

The program fragment and the output are shown. State the highest possible value for q.
Program Fragment int i = 0; while (i++
