How to return user input (string) to where only the first letter is capitalized

Question

Such as

Scanner keyboard = new Scanner(System.in);

String  productName1, productName2;
System.out.println("First product's info: ");
System.out.print("Product name: ");
productName1 = keyboard.nextLine();
System.out.println("");
System.out.println("Second product's info: ");
System.out.print("Product name: ");

How would I go about making it to where, when the user, per-say, types in aPPles as productName1. When i reprint it later, how would I make the system print it was Apples. User input print :aPPles reprint: Apples

[What have you tried?](http://mattgemmell.com/what-have-you-tried/) String class contains a lot of usefull methods like `substring` `toUpperCase` `toLowerCase`. — Pshemo, Sep 23 '15 at 23:28
Yeah but it all seems like there had to be an easier way rather than just System.out.print("|" + productName1.substring(0, 1).toUpperCase() + productName1.substring(1) + productname1.substring(1,4) + productName1.subtring(4); — DancingDylan, Sep 23 '15 at 23:33

Use

productName1 = productName1.toLowerCase();  //To lower case
productName1 = productName1.substring(0,1).toUpperCase().concat(productName1.substring(1));

This first takes the string and makes it lower case. Then it takes the first letter, makes it uppercase and adds rest of the string to it.

Thanks! What does concat do? – DancingDylan Sep 23 '15 at 23:38
It is the same as adding Strings, or connecting them together. For example, `"Dancing".concat("Dylan")` will return the String DancingDylan. – DarkHorse Sep 23 '15 at 23:50

Try this

public static void main(String[] args) {
    Scanner keyboard = new Scanner(System.in);
    String  productName1;
    System.out.println("First product's info: ");
    System.out.print("Product name: ");
    productName1 = keyboard.nextLine();
    System.out.print("Product name: ");
    productName1 = productName1.toLowerCase();
    productName1 = Character.toUpperCase(productName1.charAt(0)) + productName1.substring(1);
    System.out.println(productName1);
    keyboard.close();

}
