Array ordering in Java (Quick sort, bubble sort, select sort) _java

1. Use the sort () in the arrays class in the Javaapi document to sort quickly

Copy Code code as follows:

Import Java.util.Arrays;

public class testone{

public static void Main (String [] args) {

int [] array={2,0,1,4,5,8};

Arrays.sort (array);//Call Arrays static method sort, sorted in ascending order

for (int show:array) {

System.out.println (show);

}

}

}

2, bubble sort

Copy Code code as follows:

public class testtwo{

public static void Mian (String []args) {

int [] arr={2,0,1,4,6,5};

int [] Showarr testMethod (arr);

for (Show:showarr) {

System.out.println (show);

}

}

public static int [] TestMethod (int [] array) {

for (int x=0;x<array.length-1;x++) {

for (int y=x+1;y<array.length;y++) {

if (array [x]>array[y]) {

int temp=array[x];//temporary variable record maximum value

Array[x]=array[y];

Array[y]=temp;

}

}

}

return array;

}

}

3, select the sort

Copy Code code as follows:

public class testtwo{

public static void Mian (String []args) {

int [] arr={2,0,1,4,6,5};

int [] Showarr testMethod1 (arr);

for (Show:showarr) {

System.out.println (show);

}

}

public static int [] TESTMETHOD1 (int [] array) {

for (int x=0;x<array.length-1;x++) {

int min=x;//Set the following table to the minimum value of x

for (int y=x+1;y<array.length;y++) {

if (Array[max]>array[y]) {

Min=j

}

}

if (min!=x) {

int temp=array[x];

Array[x]=array[min];

Array[min]=temp;

}

}

return array;

}

}
