i was wondering what does num.length method does ?



import java.util.*;

public class array2{
public static void main(String[] args){
int num[] = {50,20,45,82,25,63};
int l = num.length; <--------
int i,j,t;
System.out.print("Given number : ");
for (i = 0;i < l;i++ ){
System.out.print(" " + num[i]);
}
System.out.println("\n");
System.out.print("Accending order number : ");
Arrays.sort(num);
for(i = 0;i < l;i++){
System.out.print(" " + num[i]);
}
}
}
