Java Arrays sort 从大到小排列 java array.sort Java8-Arrays.sort Arrays.sort是我们常用来排序数组的方法,不止如此,其实Collections.sort方法中也是直接拿到集合中的元素数组作为入参直接调用Arrays.sort方法的。 所以作为JDK中的常驻API,底层中对排序的各个场景是做了对应的优化算法的,使Arrays.sort在默认使用的...
1. 数字排序 int[] intArray = new int[] { 4, 1, 3, -23 }; Arrays.sort(intArray); 输出: [-23, 1, 3, 4] 2. 字符串排序,先大写后小写 String[] strArray = new String[] { "z", "a", "C" }; Arrays.sort(strArray); 输出: [C, a, z] 3. 严格按字母表顺序排序,也就是...
