    Default I have one error on a 2 simple codes.

    I have 1 error in both of these. It's an extra credit assignment. This is my first time coding with Java and I don't know what to fix because when I compile it, it says one error and it wont run.

    The First One:

    public static void main(String args[]){ 
    String firstName = "Tim"; 
    String lastName; 
    lastName = "blankityBlankBlank"; 
     
    System.out.println(Tim + "\n\n"); 
    System.out.println(blankityBlankBlank); 
     
    }


    The second one

    public static void main(String args[]){ 
    boolean leapYear = false; 
     
    for(int year = 1900; year <= 2013; year++){ 
    if(year % 400 == 0){ 
    leapYear = true; 
    }else if(year % 100 == 0){ 
    leapYear = false; 
    }else if(year % 4 == 0){ 
    leapYear = true; 
    }else{ 
    leapYear = false; 
    } 
     
    if(leapYear == true){ 
    System.out.println(year + " is a leap year"); 
    } 
     
    } 
    }

    If someone could help me out with these that would be great. Pretty urgent need to send it in tonight.

    Please copy the full text of the error message and paste it here. It has important info about the error.

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE HERE
    [/code]
    to get highlighting and preserve formatting.

    Both of the sections of posted code are missing the class definitions.

    Declaring Classes (The Java™ Tutorials > Learning the Java Language > Classes and Objects)

    I read that and put Class Name { in front of it and put a another bracket at the end and it didn't work. Maybe i'm just missing a step, I'm quite bad at this stuff.

    Default Re: I have one error on a 2 simple codes.

    Ok I think I've gotten the second one correct.
    The error for the first one is.

    ----jGRASP exec: javac -g Name.java
    Name.java:3: cannot find symbol
    symbol : class string
    location: class Name
    public static void main(string args[]){
    ^
    Name.java:7: cannot find symbol
    symbol : method printnln(java.lang.String)
    location: class java.io.PrintStream
    System.out.printnln(firstName + "\n\n");
    ^
    2 errors

    ----jGRASP wedge: exit code for process is 1.
    ----jGRASP: operation complete.

    Java is case sensitive. Make sure the names of the classes are spelled correctly. Compare the one that works with the one that doesn't. Also the ^ will point near the problem.

    I've fixed some of the stuff and have this right now

    public class Name
    {
    public static void main(String args[]){
    String firstName = "Tim";
    String lastName;
    lastName = "Kleinknecht";
    Systemoutprintnln(firstName + "\n\n");
    Systemoutprintln(lastName);
     
    }
    }

    and am getting the error

    ----jGRASP exec: javac -g Name.java
    Name.java:7: cannot find symbol
    symbol : method Systemoutprintnln(java.lang.String)
    location: class Name
    Systemoutprintnln(firstName + "\n\n");
    ^
    Name.java:8: cannot find symbol
    symbol : method Systemoutprintln(java.lang.String)
    location: class Name
    Systemoutprintln(lastName);
    ^
    2 errors

    take a look at what I wrote originally at the top
    Not sure what I'm supposed to look for in the first post.
    The code has compiler errors that need to be fixed. I gave a hint in my last post: Check the spelling.
