regd "class,interface or enum expected error" in java

[kirthi kumari]

i donot find any errors,but for almost 18lines of the code am getting an error saying "class,interfac e or enum expected error".please look at the code below


package NQ;
import java.util.Rando m;
public class CGAQueen
{
CGAQueen(int chlen)
{

len=chlen;

}
int len;
int popusize;
int mrate;
public static int [][] chromosomeMatri x=new int[30][100];

void Initpopu();
public static void main(String args[])
{

CGAQueen c=CGAQueen(8);
c.Initpopu();
return 0;
}

};

void Initpopu()
{
Random random=new Random();

boolean bcheck;
for(int index=0;index<= popusize-1;index++)

for(int a=0;a<len;a++)
{

bcheck=true;
for(int b=0;b<a;b++)
int myInt=randGen.n extInt();
if(myInt%len==c hromosomeMatrix[b][index])
bcheck=false;
if(bcheck)

chromosomeMatri x[a][index]=myInt%len;
else
a--;
}

}
