Exactly like that. No, seriously, just like you did above, but you need to add a name for your method:

public String MethodName (String Input)
{
    String a = "a";
    a += Input;
    return a;
}

Then you can call your method like:

String sample = MethodName("input");

This is not related to Android in any way.

In Java this is how you declare a method:

<visibility> <some identifiers like static, final> <return type> <name>(<arguments>)
{
     <body>
}

If the return type is void you can avoid the return. If it's something else you should always return something from the function using return

So your code here miss

public String (String Input)
{
    String a = "a";
    a += Input;
    return a;
}

This method takes a String input and returns the merge with a and the string passed when the method is called.

Example:

<functionName>("Hello");

the output will be aHello

Example:

public String test(String Input)
{
    String a = "a";
    a += Input;
    return a;
}

String output = test("World");

the output variable will be aWorld
