Example program with arrays

// Read in a list of integer grades, preceded by the

// number of grades, and print in them in reverse order

int n= Integer.parseInt(stdin.readLine()); // number of grades

int[ ] g= new int [n]; // g[0..n-1] are the grades

// Read in the grades

int i= 0;

while (i != g.length) {

g[i]= Integer.parseInt(stdin.readLine()); i= i+1; }

// Print grades in reverse order

int k= n;

while (k > 0) {

System.out.println(g[k - 1]); k = k-1; } }
