Scanner sc=new Scanner(System.in);
System.out.print("Enter First String : ");
s1=sc.nextLine();
System.out.print("Enter Second String : ");
s2=sc.nextLine();

String s3=s1+s2;
System.out.println("Result : "+s3);
int l=s3.length();
System.out.println("Length : "+l);
String s4=s3.toUpperCase();
System.out.println("Result upper : "+s4);

System.out.print("Enter character : ");
int a=System.in.read();
System.out.println((char)a);
