Sorting in Java – Video Tutorial

Learn about Array Sorting in Java Programming!

Generally, there are two types of Sorting in Java, they are,

1.Selection Sort

2.Bubble Sort

1.Selection Sort

class SelectionSort
{
static void test()
{
int[] arr = {1,5,45,23,47,25,45}; //initializing an integer type array
int n = 7; //n = no. of elements in the array
for(int i = 1;i<=n;i++) //performing the logic ‘n’ types
{
for(int j=0;j<(n-1);j++)
{
int a = arr[j]; //storing the element at ‘j’ th position in the variable ‘a’
int k = j+1; //keeping the value of ‘k’ ahead of one position with respect to ‘j’
int b = arr[k]; //storing the element at ‘k’ th position in the variable ‘b’

if(b<a) //if the condition is satisfied, then control goes inside the loop
{ //exchanging the positions of the elements of array.
int temp1=a; //storing the value of a in temporary variable temp1
int temp2=b; //storing the value of a in temporary variable temp2

arr[j] = temp2; //replacing the existing element at ‘j’ th postion with the new integer element ‘temp2’
arr[j+1] = temp1; //replacing the existing element at ‘j+1’ th postion with the new integer element ‘temp2’

}
}
}
for(int d = 0;d<7;d++) //Printing out the sorted array in ascending order
System.out.print(arr[d]+ ” “);
}
}

2.Bubble Sort

class BubbleSort
{
static void test()
{
int arr[] = {23,58,47,2,156,847,12}; //intializing an integer type array array
int n = 7; //n = no of elements in the array

System.out.println(“The Sorted Array is “);
for(int i=0;i<=(n-1);i++) //Iterating the logic (n-1) times
{
for(int j=0;j<6;j++) //Making changes with the array
{
int k = j+1;
int a = arr[j];
int b = arr[k];
if(b<a) //Comparing adjacent elements of the array
{
int temp1 = a; //storing the value of a in temp1
int temp2 = b; //storing the value of b in temp2
arr[j] = b; //exchanging posistions
arr[k] = a; //exchanging posistions
}

}
}
for(int d = 0;d<7;d++) //Printing the sorted array
System.out.print(arr[d]+” “);
}
}

Program in Java to Accept a Sentence from the user, and store each word of the Sentence in an Array.

Sample Input : Loyola Public School

Sample Output : The Elements of the Array are : Loyola, Public, School

 

import java.util.*;
class StringArray
{
static void teja()
{
Scanner in = new Scanner(System.in);
System.out.println(“Enter the sentence :”);
String st = in.nextLine();
st = st+” “;
int l = st.length();
int k =0;
for(int i=0;i<l;i++)
{
char ch = (char)st.charAt(i);
if(ch==32)
k++;
}
if(k==0)
{
System.out.println(“Please Enter a Sentence with atleast 2 words”);
}
else
{
int temp = 0;
int temp1 = 0;
String[] arr = new String[k];
for(int i = 0;i<st.length();i++)
{
char ch = (char)st.charAt(i);
if(ch==32)
{
arr[temp] = st.substring(temp1,i);
temp1 = i;
temp++;
}
}
System.out.println(“Elements of the Array are : “);
for(int i=0;i<arr.length;i++)
System.out.print(arr[i]+”, “);
}
}
}
