Non-static method cannot be referenced from a static context

[Worldofwar]

Hi,

Help will be appreciated ALOT.

These are my codes:

redTeam.java

package com.rs2hd.teams;

import java.io.*;

public class redTeam extends RandomAccessFile {

	// constructor
	Counter(String red) throws IOException {
		super(new File(red), "rw");
		writeInt(0);
	}

	public void addToCounter() {
		addToCounter(1);
	}
	
	public void addToCounter(int delta)  {
		try {
			int n = getValue() + delta;
			seek(0);
			writeInt(n);
		}
		catch(IOException e) {}
	}

	public int getValue() {
		try {
			seek(0);
			return readInt();
		}
		catch (IOException e) {}
		return -1;
	}
}

greenTeam.java

package com.rs2hd.teams;

import java.io.*;

public class greenTeam extends RandomAccessFile {

	// constructor
	Counter(String green) throws IOException {
		super(new File(green), "rw");
		writeInt(0);
	}

	public void addToCounter() {
		addToCounter(1);
	}
	
	public void addToCounter(int delta)  {
		try {
			int n = getValue() + delta;
			seek(0);
			writeInt(n);
		}
		catch(IOException e) {}
	}

	public int getValue() {
		try {
			seek(0);
			return readInt();
		}
		catch (IOException e) {}
		return -1;
	}
}

blueTeam.java

package com.rs2hd.teams;

import java.io.*;

public class blueTeam extends RandomAccessFile {

	// constructor
	Counter(String blue) throws IOException {
		super(new File(blue), "rw");
		writeInt(0);
	}

	public void addToCounter() {
		addToCounter(1);
	}
	
	public void addToCounter(int delta)  {
		try {
			int n = getValue() + delta;
			seek(0);
			writeInt(n);
		}
		catch(IOException e) {}
	}

	public int getValue() {
		try {
			seek(0);
			return readInt();
		}
		catch (IOException e) {}
		return -1;
	}
}

These are the errors I get:

1.add public (or some other based upon your design) identifier before the constructor name declaration, and if you are returning a value in the method signature you have to make sure that u use return zzzz; at the end of the method inside its body
2:Again if you want to access a static method you should use as ClassName.StaticMethod instead.
