Here is an example of generating two-dimensional array.

```import java.util.*;

public class twoDimension{
public static void main(String[] args) {
Scanner input=new Scanner(System.in);
System.out.print("Enter value of i: ");
int a=input.nextInt();

System.out.print("Enter value of j: ");
int b=input.nextInt();

int[][] a2 = new int[a][b];
System.out.println("Enter elements of your choice: ");
for(int i=0 ; i < a2.length ; i++){
for(int j=0 ; j < a2[i].length ; j++){
a2[i][j] = input.nextInt();
}
}
for(int i=0 ; i < a2.length ; i++){
System.out.println();
for(int j=0 ; j < a2[i].length ; j++){
System.out.print(a2[i][j]+" ");
}
}
}
}
```
