1)public class Palindr{  
 
public static void main(String[] args) {
 
String str="MADAM";
String revstring="";
 
for(int i=str.length()-1;i>=0;--i){
revstring +=str.charAt(i);
}
 
System.out.println(revstring);
 
if(revstring.equalsIgnoreCase(str)){
System.out.println("The string is Palindrome");
}
else{
System.out.println("Not Palindrome");
}
 
}
}
2)public class Pattern
{
    public static void main(String args[])
    {
        int i, j;
        for(i=0; i<5; i++)
        {
            for(j=0; j<=i; j++)
            {
                System.out.print("* ");
            }
