Max and Min of 3 values using args[] in Java with Windows cmd

Question

While compiling I got this

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0

class Maxmin {
public static void main(String args[]) {
    if (args.length >0) {


    int a = Integer.parseInt(args[0]);
    int b = Integer.parseInt(args[1]);
    int c = Integer.parseInt(args[2]);
    int tmp;
if (a>b) {
    tmp=a ;a=b ;b=tmp;

    }
if (b>c) {
    tmp=b ;b=c ;c=tmp;
}
if (a>c) {
    tmp=a ;a=c;c=tmp;
}
        System.out.println (a);

}
 }
 }
