Arrays in Python and Java, Jumping from one programming language to…

- - - - Array
        
        Creation and Initialization
        
        int[] anArray;
        
        int[] anArray = new int[5];
        
        int[] anArray = new int[] {1, 2, 3, 4, 5};
        
        int anArray[];
        
        int[] anArray = new Integer[5];
        
        Get the size
        
        anArray.length
        
        java.lang.reflect.Array.getLength(anArray);
        
        Access Elements
        
        anArray[0]
        
        Definite Iterating
        
        for (int i = 0; i < anArray.length; i++) { ... }
        
        for (int element : anArray) { ... }
        
        Converting
        
        List<Integer> aList = Arrays.asList(anArray);
        
        Stream<String> aStream = Arrays.stream(anArray);
        
        Sorting
        
        Arrays.sort(anArray);
  - - - tuple
        
        Creating and Initializing
        
        one_item_tuple = 1,
        
        tuple_from_string = tupĺe('danger!')
        
        empty_tuple = tuple()
        
        empty_tuple = ()
        
        one_item_tuple = (1,)
        
        tuple_from_list = ([1,2])
        
        Accessing elements
        
        tuple[1]
- - - - numpy.array
    - - java.util.ArrayList
      - java.util.vector
  - - - list
        
        Creating and Initializing
        
        numbers = [1, 2, 3, 4, 5]
        
        list_out_of_string = list('danger!')
        
        empty_list = list()
        
        empty_list = []
        
        Getting the Size
        
        len(myList)
        
        Definite Iterating
        
        for(element in myList)
        
        Handling elements
        
        Getting one by index
        
        myList[0]
        
        Adding one
        
        append
        
        myList.append(newElement)
        
        insert
        
        myList.insert(1 , newElement)
        
        Adding several
        
        myList.extend(anotherList)
        
        myList += anotherList
        
        newList = myList * 3
        
        Removing
        
        First instance of a value
        
        myList.remove("element")
        
        By index
        
        del myList[1]
        
        Remove and return
        
        last
        
        pop()
        
        by index
        
        pop(1)
