class bubbleSort1{


public static void bubbleSort(int[] x) {
int n = x.length;
for (int pass=1; pass < n; pass++) { // count how many times
// This next loop becomes shorter and shorter
for (int i=0; i < n-pass; i++) {
if (x > x[i+1]) {
// exchange elements
int temp = x; x = x[i+1]; x[i+1] = temp;
}
}
}
}
}
the output say..

java.lang.NoSuchMethodError: main
Exception in thread "main"

The class that you're trying to run doesn't have an entry point (main) method.

Try declaring this method in your class--

public static void main(String[] args){


}

-- also please use code tags.

in your programeme no main function
so youcan compile it
bu u can't run that programme
see syntax

import java.io.*;
class bubbleSort1{
public int x[],max;


public void input()throws IOException
{
DataInputStream in=new DataInputStream(System.in);
System.out.println("Enter the Limit:");
max=Integer.parseInt(in.readLine());
x=new int[max];
for (int pass=0; pass <max; pass++)
{
System.out.print("Enter the value for "+pass+" element :" );
x[pass]=Integer.parseInt(in.readLine());
}
}


public void bubbleSort() {

for (int pass=0; pass < max; pass++) {
for (int i=1; i < max-pass; i++) {
if (x[i-1] > x) {
// exchange elements
int temp = x[i-1]; x[i-1] = x; x = temp;
}
}
}
}


void result()
{
for (int pass=0; pass < max; pass++)
{
System.out.println(x[pass]);
}
}


public static void main(String agr[])
{

bubbleSort1 obj= new bubbleSort1();
try
{
obj.input();
obj.bubbleSort();
obj.result();
}
catch(Exception e)
{System.out.println(e);}
}
}


In ur coding there is no main method thats wy that problem occured.

import java.io.*;
class bubbleSort1{
public int x[],max;


public void input()throws IOException
{
DataInputStream in=new DataInputStream(System.in);
System.out.println("Enter the Limit:");
max=Integer.parseInt(in.readLine());
x=new int[max];
for (int pass=0; pass <max; pass++)
{
System.out.print("Enter the value for "+pass+" element :" );
x[pass]=Integer.parseInt(in.readLine());
}
}


public void bubbleSort() {

for (int pass=0; pass < max; pass++) {
for (int i=1; i < max-pass; i++) {
if (x[i-1] > x) {
// exchange elements
int temp = x[i-1]; x[i-1] = x; x = temp;
}
}
}
}


void result()
{
for (int pass=0; pass < max; pass++)
{
System.out.println(x[pass]);
}
}


public static void main(String agr[])
{

bubbleSort1 obj= new bubbleSort1();
try
{
obj.input();
obj.bubbleSort();
obj.result();
}
catch(Exception e)
{System.out.println(e);}
}
}

oh! very nice that your programme is properly running.what did happen to this.
