(java) Calculation to make player follow mouse(doesn't work)

Xdif = Anaglyph.mouseX - playerX-25;
Ydif = Anaglyph.mouseY - playerY-25;

angle = Math.atan2(Ydif, Xdif) * 180 / Math.PI;

dX = Math.cos(angle * Math.PI/180) * 10;
dY = Math.sin(angle * Math.PI/180) * 10;

playerX = ((playerX-mouseX)*(playerX+dX-mouseX) > 0 && playerX != mouseX) ? playerX+dX : mouseX;
playerY = ((playerY-mouseY)*(playerY+dY-mouseY) > 0 && playerY != mouseY) ? playerY+dY : mouseY;
