How to make test cases satisfy the condition coverage standard?

Design test cases for the program below.And make the test cases satisfy the condition coverage standard.

 public void work ( int x, int y, int z ) {  

1 int k = 0, j = 0;

2 if ( (x>3) && (z<10) ){

3 k = x * y - 1;

4 j = sqrt ( k );

5 }

6 if( ( x==4 ) || ( y>5 ) )

7 j = x * y + 10;

8 j = j % 3;

}
