Programmers want to handle a multitude of business logic by random numbers, and the test process

Look for a "combination of numbers and letters and spaces" in an input string, noting that the three appear at the same time, or that only numbers and letters appear without spaces.For example, input "HG 437 djj third dufwf745, DFN^894DK Big Brother-in-law iphone 6s74854"Output:HG 437 DJJdufwf745894dkIPhone 6sThe following code can be implemented1String s = "Hg 437 djj third dufwf745, DFN^894DK Big Brother-

This article brings you the content is about Java instance: 6x6 Gongge Two diagonal numbers of the sum of the calculation (code), there is a certain reference value, the need for a friend can refer to, I hope to help you.

This paper mainly introduces 3 kinds of methods of obtaining random number in Java, mainly using random () function to realize Method 1 (data type) (Minimum +math.random () * (maximum-min +1)) Example: (int) (1+math.random () * (10-1+1)) from 1 to 10 int type with number Method 2 Get random numbers for (int i=0;i Through Java. The ra
