I keep getting the error Picked up JAVA_TOOL_OPTIONS: -Xmx128m and the code wont compile

I've found a couple other threads on the forum which weren't really helpful at all. I can't compile or run any programs and I'm sure I'm typing everything in correctly. I don't know what to do at this point. I'm running Windows 10 64 bit.

the printf() method expects 2 or more arguments: a format and the rest of arguments. To print what you wanted there you should use the simple print() method like this:

import java.io.Console;

public class Introductions {

public static void main(String[] args) {
    Console console = System.console();
    // Welcome to the Introductions program!  Your code goes below here
    console.print("Hello, my name is Geoffrey");

} }

The printf method work something like this: 

import java.io.Console;

public class Introductions {

public static void main(String[] args) {
    Console console = System.console();
    // Welcome to the Introductions program!  Your code goes below here
     String myName = "Geoffrey";
    console.printf("Hello, my name is %s", myName);

} }

if you copy any of this it should run. Please let me know if there are any other problems.

} }
