Answer 1

CODE :

import java.util.*;

class digits_ascending

{

public static void main(String args[])

{

Scanner sc=new Scanner(System.in);

System.out.println("Enter a number");

int n=sc.nextInt();

int cpy1=n;

int d=0;

int c=0;

while(cpy1>0)

{

cpy1=cpy1/10;

c++;

}    

int cpy2=n;

int i=0;

int a[]=new int[c];

while(cpy2>0)

{

d=cpy2%10;

a[i]=d;

i++;

cpy2=cpy2/10;

}

int min=0;

int temp=0;

for(i=0;i<(c-1);i++)

{

min=i;

for(int j=i+1;j<c;j++)

{

if(a[j]<a[min])

{

min=j;

}

}

temp=a[i];

a[i]=a[min];

a[min]=temp;

}

System.out.println("The digits are printed in ascending :");

for(i=0;i<c;i++)

{

System.out.println(a[i]);

}

}

//end of main

}//end of class

OUTPUT :

Enter a number

The digits are printed in ascending :
