Copy/paste this code into a file StringTest.java
:
import java.awt.*;
import java.io.*;
// the program demonstrates various methods
// of class String
// Unlike StringBuffer, String value doesn't change in
// memory. String methods return a new string which can be assigned
// to the same variable or to a different one.
public class StringTest {
public static void main (String [] args) throws IOException{
// set up the program for reading data
// Create a buffered reader
BufferedReader in = new BufferedReader(
new InputStreamReader(System.in));
// create a string variable (it doesn't refer to any object)
String input;
System.out.print("What's your name? ");
input = in.readLine();
// format the name: first letter capital, the rest lower case:
// create the string with just the first letter:
String first = input.substring(0,1);
// create another string with the first letter in upper case:
first = first.toUpperCase();
// create the string with the rest:
String therest = input.substring(1);
// create a string with the lower-case version
// of the rest of the name:
therest = therest.toLowerCase();
String result = "Nice to meet you, " + first + therest;
System.out.println(result);
}
}
This is an example from CSci 1211 course.
