Hi Friend,

1)Prime Numbers
class PrimeNumbers{
public static void main (String args[]){
String primeNo = "";
int j=0;
System.out.println("Prime Numbers are:" );
for (int i = 1; i < 100; i++){ {
for ( j = 2; j < i; j++){
if (i % j == 0) {
break;
}
}
if (i == j) {
primeNo += i + " ";
}
}
}
System.out.println(primeNo);
}
}

2)Reverse Number
import java.util.*;

public class ReverseNumber{
public static void main(String[]args){
Scanner input = new Scanner(System.in);
System.out.println("Enter number");
int number = input.nextInt();
int reverseNumber = Integer.parseInt( new StringBuffer( ""+number ).reverse().toString() );
int incrementedNumber=reverseNumber+1;
System.out.println("Reversed Number= "+reverseNumber);
System.out.println("Incremented Number= "+incrementedNumber);
}
}

3)String
class Program1{
public static void main(String[] args) {
String st="STRING";
String s=st.toLowerCase();
char c=s.charAt(0);
System.out.println(c);
char ch[]=st.toCharArray();
for(int i=1;i<ch.length;i++){
System.out.println(ch[i]);
}
st = new StringBuffer(st).reverse().toString();
char ch1[]=st.toCharArray();
for(int i=1;i<ch1.length;i++){
System.out.println(ch1[i]);
}
}
}

Thanks
