You should know how to....

Declare a class

public class Person {}

Declare a variable (int, double, String, View)

int i;
double d = 10;
String s = "";
View v = new View();

Declare an array

double [] D = new double[20];
int [] I = new int[x];

Create a loop

for(int i = 0; i < 10; i++){...}
while(x < 10) {...}

Preform mathematical expressions

x = y + 7;
x = n * 8 - 2;

Create if statements

if ( x == 8) {...}
if (y > 9 ){...}

Use Arrays

a[i] = v.getInt("Enter...");
a[i] = 10;
if(a[i] > 4) {...}
