According to the Java Code Conventions as defined by Oracle, the members of a class or interface declaration should appear in the following order in the source files:
public class Foo{
private int field = 0;
public boolean isTrue() {...}
public Foo() {...} // Noncompliant, constructor defined after methods
public static final int OPEN = 4; //Noncompliant, variable defined after constructors and methods
}
public class Foo{
public static final int OPEN = 4;
private int field = 0;
public Foo() {...}
public boolean isTrue() {...}
}
