through command line
example
class test
{
public static void main ( String args [ ] )
{
// for loop to access all command line arguments
for (int i = 0 ; i < args.length ; i ++)
{
System.out.println ("Argument " + (i +1) + " : " + args [i]) ;
} // for loop ends
} // main function ends
} // class ends
Run this class as following
java test one two three
- Whatever comes after the name of class (seperated by space) , goes into the parameter args which is a String array
- for loop runs as long as there are elements in the array args which depends on how many we pass
Output: Argument 1 : one
Argument 2 : two
Argument 3 : three
args [ 0 ] holds one
args [ 1 ] holds two
args [ 2 ] holds three
