Write a program using BlueJ to print the prime numbers from 2 to 100.
{
public void show()
{
System.out.println("\nPrime numbers between 2 and 100 are as follows:");
for( int i=2;i< =100;i++)
{
if(prime(i))
System.out.print(" " + i);
}
}
public boolean prime(int n)
{
int i;
for(i=2;i< n;i++)
{
if(n%i==0)
break;
}
if(i==n)
return true;
else
return false;
}
}
Write a program using BlueJ to find the largest even number and smallest odd number from a list of 'n' numder of terms given by the user and indicates the number of numerals to be accepted.
import java.io.*;
class BlueJ1
{
int arr[],n,max,min;
BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
public void takeData()throws IOException
{
System.out.println("\nEnter the number of values to be stored:");
n=Integer.parseInt(br.readLine());
arr=new int[n];
for( int i=0;i< n;i++)
{
System.out.print("Enter value: " );
arr[i]=Integer.parseInt(br.readLine());
}
}
public void show()
{
max=1;
min=2;
for(int i=0;i< n;i++)
{
if(arr[i]%2==0 && max==1)
max=arr[i];
else if(arr[i]%2!=0 && min==2)
min=arr[i];
else if(arr[i]%2==0 && arr[i]>max)
max=arr[i];
else if(arr[i]%2!=0 && arr[i] < min)
min=arr[i];
}
System.out.println("Minimum odd Number="+min);
System.out.println("Maximum even Number="+max);
}
}
class BlueJ2
{
public void show()
{
System.out.println("The numbers which are prime and palindrome are:");
for( int i=100;i< =500;i++)
{
if(palin(i) && prime(i))
System.out.print(i+ " " );
}
}
public boolean prime(int n)
{
int i;
for(i=2;i< n;i++)
{
if(n%i==0)
break;
}
if(i==n)
return true;
else
return false;

public boolean palin(int n)
{
int r=0;
for(int i=n;i >0;i=i/10)
{
r=r*10+i%10;
}
if(r==n)
return true;
else
return false;
}
}
Write a program using BlueJ to print the multiplication table from 11-15
{
public void show()
{
System.out.println("The Multiplication Table from 11 to 15 as follows:");
for( int i=11;i< =15;i++)
{
for(int j=1;j< =10;j++)
{
System.out.print(i*j+ " " );
}
System.out.println();
}
}
}
can anyone pls help wid this pattern:

6 12
6 12 18
6 12 18 24.....till 'n' number of terms
Pl. check the posting of October 12,2010. You will get lot of programs including this program.

Can we provide time limit in blueJ cauze i am making a program of writing test sort of program where the user will have to write the following give lines given by me in a specific time, how will i??? this is just a beta vs. of my program.
ReplyDeleteThis can be done easily in java using Thread. As thread is not included in ISC syllabus, I am not posting such a program here. If you need help, I can send the code to you
