A 28-year-old male sustained a cut on his hand while slicing carrots for a stew. The wound that he sustained is called a(n):

The sinking of the RMS Titanic fueled research that would change the science of bathymetry.

What was called “The unifying theory” because it explains how the continents and oceans have been shaped with earthquakes, mountains, volcanoes and tsunamis?

First, note that String and Integer are both immutable. Is the class below mutable or immutable? If mutable: a) provide client code that will mutate it; and b) provide an immutable version of it (your solution has to be minimal, i.e., make the minimal changes possible, or you might loose points). If immutable, provide a convincing argument why it is so.     class SomeClass {     public String string;     public Integer n;         public SomeClass(String string, int n) {         this.string = string;                             this.n = n;                                   }       public String getString() { return string; }      public Integer getInt()    { return n; }       }

Is StackOverflowError checked or unchecked? Explain why it is one or the other.

The function below is meant to return the first index i at which a == b. E.g. firstDuplicate(, ) = 1. Given the precondition: ((a != null)&&(b != null)). Provide the postcondition   public static int firstDuplicate(int b)    // Precondition:      ((a != null)&&(b != null))    // Postcondition:             

The function below is meant to return the first index i at which a == b. E.g. firstDuplicate(, ) = 1. Provide a specification such that: 1) The precondition is very strong. 2) The postcondition cannot throw any exceptions or return any integer that indicates that a duplicate does not exist.   public static int firstDuplicate(int b)    // Precondition:                          // Postcondition:
