Java Programming

Question is given main class which is
import java.util.Scanner;

public class PascalDriver{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
System.out.println("Enter number of rows");
int rowCount = scan.nextInt();
PascalTri t = new PascalTri(rowCount);
t.displayRows();
}
}

then ask me to right a class which is named PascalTri

that is what I get:
public class PascalTri {
int triangle[][]=new int[rows][rows];
for(int i=0;i<rows;i++){
for(int j=0;j<rows;j++){
triangle[i][j]=0;
triangle[0][0]=1;
triangle[1][0]=1;
triangle[1][1]=1;
for(int i=2;i<rows;i++){
triangle[0]=1;
for(int j=1;j<=i;j++){
triangle[i][j]=triangle[i-1][j-1]+triangle[i-1][j];
}
public displayRows(){
return triangle[i][j];
}}}}

is it right? I donot know y dr.java says "for(int i=0;i<rows;i++){ "is an error, I donot know y, can anyone help me?
