50.Write a Java program to sort an array of positive integers from an array. In the sorted array the value of the first element should be maximum, the second value should be a minimum, third should be the second maximum, the fourth should be the second minimum and so on. Click me to...
Concept: Each element in an array is a one-dimensional array, and the array is called a two-dimensional array.静态初始化：Static initialization:动态初始化：Dynamic initialization:注：其中列个数可以省略不写，因为Java中的二维数组存在不规则矩阵这样的数组，因此写了也没有多大意义。Note: The number of...

one-dimensional array is faster than a two-dimensional array. Use the faster switch bytecode. Use private and static methods, and final classes, to encourage inlining by the compiler. Reuse objects. Local variables are the faster than instance variables, which are in turn faster than array ...
