Maven Build Life Cyles

Following are the maven build life cycles.

Clean - Removes the generated files in 'target' folder.

command : mvn clean

Validate - It validates your project and verify all the necessary information is there in project or not.

mvn valiate

Compile - It compiles your project code.

mvn compile

Package - It takes the compiled code and packaged to JAR/WAR/EAR. It also compiles your code if your code is not compiled.

mvn package

Install - It takes the packaged code and puts in your local maven repository (M2_HOME). It also does the compile and package if these are not already been done.

mvn install

Deploy - It takes the package and puts in remote repository for sharing accross team members or for other projects.

mvn deploy

FYI - Above commands can be used as variety of combinations.
e.g. mvn clean install
mvn clean package
mvn clean compile package install

To skip the tests to run
mvn clean install -DskipTests

Compress a String

package com.sbs.java8.praticse; public class StringCompression { public StringCompression() { // TODO Auto-generated constructor stub } public static void main(String[] args) { System.out.println(compressString("aaaabbbbbccccAAAAccccccccdefg")); } public static String compressString(String str) { //String str = "aaaabbbbbcccc"; char[] charArray = str.toCharArray(); String compressedString = ""; int i = 0; while (i < charArray.length) { int counter = 1; int j = i + 1; while (j < charArray.length && charArray[i] == charArray[j]) { counter++; j++; i++; } compressedString = compressedString + charArray[i] + counter; i++; } //System.out.println(compressedString); String output =(compressedString.length() > charArray.length)? str: compressedString; return output; } }

Basic Sortings (Bubble, Selection and Insertion Sorts)

public class BasicSortings { public static void main(String[] args) { int temp; int iterationCount = 0; int array[] = { 2, 33, 29, 30, 21, 98}; //Bubble sort or Simple sort for (int i = 0; i < array.length - 1; i++) { for (int j = i + 1; j < array.length; j++) { if (array[i] > array[j]) { temp = array[i]; array[i] = array[j]; array[j] = temp; } iterationCount++; } } System.out.println("Bubble Sort Big 0(n) --> " + iterationCount); for (int s = 0; s < array.length; s++) { System.out.print(array[s] + "\t"); } System.out.println("\n"); System.out.println("\n"); //Selection Sort iterationCount =0; int sortPointer=0; for (int i = sortPointer; i < array.length; i++) { for(int j=i+1;j< array.length;j++) { if(array[i] > array[j]) { temp = array[i]; array[i] = array[j]; array[j] = temp;
