sort array java
Here’s the java program to sort an array using Arrays.sort() method.
import java.util.Arrays;
public class JavaArraySortMethod
{
public static void main(String[] args)
{
String[] strGiven = {"Great Barrier Reef", "Paris", "borabora", "Florence","tokyo", "Cusco"};
Arrays.sort(strGiven);
System.out.println("Output(case sensitive) : " + Arrays.toString(strGiven));
}
}Arrays.sort() in java
// java sort array of objects
import java.util.Arrays;
public class Employee implements Comparable<Employee>
{
private String empName;
private int empAge;
public Employee(String name, int age)
{
this.empName = name;
this.empAge = age;
}
@Override
public String toString()
{
return "{" + "name='" + empName + '\'' + ", age=" + empAge + '}';
}
public String getName()
{
return empName;
}
public int getAge()
{
return empAge;
}
@Override
public int compareTo(Employee o)
{
if(this.empAge != o.getAge())
{
return this.empAge - o.getAge();
}
return this.empName.compareTo(o.getName());
}
}
public class SortArrayObjects
{
public static void main(String[] args)
{
Employee[] obj = { new Employee("virat", 25), new Employee("dhoni", 20),
new Employee("rohit", 22), new Employee("rahul", 24)};
Arrays.sort(obj);
System.out.println(Arrays.toString(obj));
}

import java.util.Scanner;
public class JavaExample
{
public static void main(String[] args)
{
int count, temp;
//User inputs the array size
Scanner scan = new Scanner(System.in);
System.out.print("Enter number of elements you want in the array: ");
count = scan.nextInt();
int num[] = new int[count];
System.out.println("Enter array elements:");
for (int i = 0; i < count; i++)
{
num[i] = scan.nextInt();
}
scan.close();
for (int i = 0; i < count; i++)
{
for (int j = i + 1; j < count; j++) {
if (num[i] > num[j])
{
temp = num[i];
num[i] = num[j];
num[j] = temp;
}
}
}
System.out.print("Array Elements in Ascending Order: ");
for (int i = 0; i < count - 1; i++)
{
System.out.print(num[i] + ", ");
}
System.out.print(num[count - 1]);
