PLEASE HELP ME.....
This the the the Lane Class:
import java.util.*;
import java.io.*;
import java.*;
public class Lane
{
public String[][] lane = new String[10][3];
int car1 = 0;
int car2 = 0;
int car3 = 0;
int car4 = 0;
public int bool = 1;
Random random = new Random();
public String[][] addCar()
{
while(bool == 1)
{
Random random = new Random();
int randomInt = random.nextInt(4);
if(randomInt == 0)
{
car1++;
lane[0][0] = "<=>";
moveL1();
}
if(randomInt == 1)
{
car2++;
lane[0][1] = "<=>";
moveL2();
}
if(randomInt == 2)
{
car3++;
lane[10][2] = "<=>";
moveR1();
}
if(randomInt == 3)
{
car4++;
lane[10][3] = "<=>";
moveR2();
}
return lane;
}
return lane;
}
public String[][] moveL1()
{
int i=0;
int j=1;
while(bool==1)
{
for(int a=0; a<=10; i++)
{
String temp=lane[0];
lane[0]=lane[j][0];
lane[j][0]=temp;
return lane;
}
lane[10][0] = "";
break;
}
return lane;
}
public String[][] moveL2()
{
int i=0;
int j=1;
while(bool==1)
{
for(int a=0; a<=10; i++)
{
String temp=lane[1];
lane[1]=lane[j][1];
lane[j][1]=temp;
return lane;
}
lane[10][1] = "";
break;
}
return lane;
}
public String[][] moveR1()
{
int i=10;
int j=9;
while(bool==1)
{
for(int a=0; a<=10; i++)
{
String temp=lane[2];
lane[2]=lane[j][2];
lane[j][2]=temp;
return lane;
}
lane[0][2] = "";
break;
}
return lane;
}
public String[][] moveR2()
{
int i=10;
int j=9;
while(bool==1)
{
for(int a=0; a<=10; i++)
{
String temp=lane[3];
lane[3]=lane[j][3];
lane[j][3]=temp;
return lane;
}
lane[0][3] = "";
break;
}
return lane;
}
}
And this is the Tester class:
/**
* @(#)LaneTest.java
*
*
* @Jeff Cho
* @SID 307144283
* @created 2007/4/30
*/
public class LaneTest
{
addCar car = new addCar();
}
This program is suppose to simulate how a car move on a lane (in terms of array).
The Lane Class compiled perfectly.
But the LaneTest, have 1 error:
Invalid method declaration; return type need
I dont understand why, Please help me....
