你可能想为每个类创建一个 initialize() 方法,该方法名暗示着在使用类之前需要先调用它。不幸的是,用户必须得记得去调用它。在 Java 中,类的设计者通过构造器保证每个对象的初始化。如果一个类有构造器,那么 Java 会在用户使用对象之前(即对象刚创建完成)自动调用对象的构造器方法,从而保证初始化。下个挑战是如何命...
Alternatively, you can use the shortcut syntax to create and initialize an array: int[] anArray = { 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 }; Here the length of the array is determined by the number of values provided between braces and separated by commas. ...
// initialize array with extremely far away depths for (int q = 0; q < zBuffer.length; q++) { zBuffer[q] = Double.NEGATIVE_INFINITY; } for (Triangle t : tris) { // 之前的代码 if (V3 && V2 && V1) { double depth = v1.z + v2.z + v3.z; ...
