    push 1L (the number one with type long) onto the stack ldc 12 0001 0010 1: index → value push a constant #index from a constant pool (String, int, float, Class, java.lang.invoke.MethodType, java.lang.invoke.MethodHandle, or a dynamically-computed constant) onto the stack ldc_w 13 0001 0011 2: indexbyte1, indexbyte2 → value

  3. Type conversion - Wikipedia

    Existing Eiffel software uses the string classes (such as STRING_8) from the Eiffel libraries, but Eiffel software written for .NET must use the .NET string class (System.String) in many cases, for example when calling .NET methods which expect items of the .NET type to be passed as arguments. So, the conversion of these types back and forth ...

    The term string also does not always refer to a sequence of Unicode characters, instead referring to a sequence of bytes. For example, x86-64 has string instructions to move, set, search, or compare a sequence of items, where an item could be 1, 2, 4, or 8 bytes long. [26]

  6. Primitive wrapper class in Java - Wikipedia

    en.wikipedia.org/.../Primitive_wrapper_class_in_Java

    Collection classes are Java API-defined classes that can store objects in a manner similar to how data structures like arrays store primitive data types like int, double, long or char, etc., [2] but arrays store primitive data types while collections actually store objects. The primitive wrapper classes and their corresponding primitive types are:

    The expression ((Integer) 42). toString will convert an integer literal to string in Java while 42. ToString performs the same operation in C#. This is because the latter one is an instance call on the primitive value 42, while the former one is an instance call on an object of type java.lang.Integer.

    Java: modulo power of two (char is the only unsigned primitive type in Java) modulo power of two JavaScript: all numbers are double-precision floating-point except the new BigInt: MATLAB: Builtin integers saturate. Fixed-point integers configurable to wrap or saturate Python 2 — convert to long type (bigint) Seed7 — raise OVERFLOW_ERROR [11 ...

  9. Static import - Wikipedia

    In this case, MAX_VALUE is ambiguous, as the MAX_VALUE field is an attribute of both java.lang.Integer and java.lang.Long. Prefixing the field with its class name will disambiguate the class from which MAX_VALUE is derived, but doing so makes the use of a static import redundant.
