controll an arduino robot using java netbeans

hi everyone
i made robo using arduino uno and motordriver l293d
i used the followng code in arduino api

int normalSpeed = 200; // General speed
int spinSpeed = 200; // Spins Speed
int m1=4,e1=5,m2=7,e2=6;

void setup(){
Serial.begin(9600);
}

void loop(){
if (Serial.available() > 0) {
char motors = Serial.read();
switch(motors) {
case 'w':
analogWrite(m1,0);
analogWrite(e1,normalSpeed);
analogWrite(m2,0);
analogWrite(e2,normalSpeed);
break;
case 's':
analogWrite(m1,normalSpeed);
analogWrite(e1,0);
analogWrite(m2,normalSpeed);
analogWrite(e2,0);
break;
case 'a':
analogWrite(m1,0);
analogWrite(e1,spinSpeed);
analogWrite(m2,spinSpeed);
analogWrite(e2,0);
break;
case 'd':
analogWrite(m1,spinSpeed);
analogWrite(e1,0);
analogWrite(m2,0);
analogWrite(e2,spinSpeed);
break;
case 'g':
analogWrite(m1,0);
analogWrite(e1,0);
analogWrite(m2,0);
analogWrite(e2,0);
break;
}
}
}
but i am not able to establish a connection between arduino uno and netbeans ,and also not able to send to arduino using arrow keys so that i can controll robot using netbeans interface

That sounds like a Java problem.

That sounds like a Java problem.

Sounds more like a user problem.

OP: If you posted your Java code, I'm sure someone here would trip over and say "Hey, that's Java". Might even be able to say more.
