Array1public class Array1 extends Object | Review examples of arrays: shows array allocation, processing,
storing objects in Arrays,, two-dimensional arrays, and lengths. |
| Methods Summary |
|---|
| public static void | main(java.lang.String[] argv)
int monthLen1[]; // declare a reference
monthLen1 = new int[12]; // construct it
int monthlen2[] = new int[12]; // short form
// even shorter is this initializer form:
int monthLen3[] = {
31, 28, 31, 30,
31, 30, 31, 31,
30, 31, 30, 31,
};
final int MAX = 10;
Calendar days[] = new Calendar[MAX];
for (int i=0; i<MAX; i++) {
// Note that this actually stores GregorianCalendar
// etc. instances into a Calendar Array
days[i] = Calendar.getInstance();
}
// Two-Dimensional Arrays
// Want a 10-by-24 array
int me[][] = new int[10][];
for (int i=0; i<10; i++)
me[i] = new int[24];
// Remember that an array has a ".length" attribute
System.out.println(me.length);
System.out.println(me[0].length);
