Java <identifier> expected error? -

i 20 errors in middle loops when compiling program; following snippet:

public static long[] bishopsmasks() {     long[] masks = new long[64];      (int j = 0; j < 8; j++)     {         (int = 0; < 8; i++)         {             long x = 0l;              (int = + 1, int b = j + 1; < 7 && b < 7; a++, b++)                 x |= bit(a, b);              (int = + 1, int b = j - 1; < 7 && b > 0; a++, b--)                 x |= bit(a, b);              (int = - 1, int b = j + 1; > 0 && b < 7; a--, b++)                 x |= bit(a, b);              (int = - 1, int b = j - 1; > 0 && b > 0; a--, b--)                 x |= bit(a, b);              masks[i + j * 8] = x;         }     }      return masks; } 

i can't find wrong it!

you can't declare multiple variables in for-loop initializer this:

for (int = + 1, int b = j + 1; < 7 && b < 7; a++, b++) 

you can, however, (note removal of int before b):

for (int = + 1, b = j + 1; < 7 && b < 7; a++, b++) 

however, means variables have same type, of course.

see java language specification section 14.14.1 more information.
