Yesterday, a friend suddenly asked me this question, for a moment I was speechless, just at the beginning is limited to no way to record the repeat position, as just contact with the Java language rookie, racked his brains to the most stupid way to achieve, but also hope the great God pointing out a better way.public class Test01 { public static void Main (string[] args) {Test1 ();} /*** Method Name: Test1* Method Description: An

] = (byte) ((res >> 8) 0xff);//Sub-low TARGETS[2] = (byte) ((res >>) 0xff);//Secondary high TARGETS[3] = (byte) (res >>> 24);//highest bit, unsigned right shift. return targets; } /** * Converts a byte array of length 2 to 16-bit int * * @param Res * byte[] * @return int * */ public static int Byte2int (byte[] res) { res = Inversionbyte (res); A byte data shifted left 24 bits into 0x?? 000000, then move right 8 bits in

For me, this is a matter of concern because it is stackoverflow and recommended. The people who raised such questions were widely praised, which enabled him to do many things on StackOverflow. Although it doesn't mean much to me, let's take a look at the problem first. The question is as follows: How to convert the arrays array below to a ArrayList. Element[] Array = {new Element (1), new Element (2), new

: The array element has a default value. After the array has opened up memory space, the value is assigned by default, without assigning values to the elements.

Recently, when I was working on a project, I encountered a problem of passing List sets as parameters. I remembered the previous summary of parameter passing. parameter passing includes value passing and reference passing. The parameters of the Set class should belong to reference passing, the array suddenly flashed into my mind, and I felt that the array was also a special set and should also be a referenc

pair. Each time we compare, we copy the larger numbers from the back to the secondary array, making sure the numbers in the auxiliary array are ascending. After copying the larger number to the array, move the corresponding pointer forward one bit, then proceed to the next round of comparisons.After the detailed discussion above, we suspect summed up the process

In Java, ArrayList and vectors store data in an array that is larger than the actual stored data in order to add and insert elements, allowing direct ordinal index elements, but inserting data to design memory operations such as array element movement, so the index data quickly inserts data slowly, Vector because of the use of the Synchronized method (thread safe
