What is faster in Java. Accessing an array index directly multiple times, or saving the value of the array index to a new variable and use this for following compution?
acces index
if ((shape.vertices[0].x >= fromX && shape.vertices[0].x <= toX) || // left side of shape in screen
(shape.vertices[0].x <= fromX && shape.vertices[0].x + shape.width >= fromX) || // right side of shape in screen
(shape.vertices[0].x >= fromX && shape.vertices[0].x + shape.width <= toX)) { // shape fully in screen
// ...
}
temp variable
float x = shape.vertices[0].x;
float y = shape.vertices[0].y;
if ((x >= fromX && x <= toX) || // left side of shape in screen
(x <= fromX && x + shape.width >= fromX) || // right side of shape in screen
(x >= fromX && x + shape.width <= toX)) { // shape fully in screen
// ...
}
