according to the scientific notation. for example, 1.23x109 and 12.3x108 are equal. Floating point numbers can be written in mathematics, such as 1.23, 3.14,-9.01, and so on. However, large or small floating point numbers must be represented by scientific notation, replacing 10 with e. 1.23x109 is 1.23e9, or 12.3e8, 0.000012 can be written as 1.2e-5. Integers and floating-point numbers are stored in computers in different ways. integer operations are always accurate (is division accurate? Yes !

use the Contentresolver.update () method to modify the data, and we'll write a way to modify the data:private void UpdateRecord (int recNo, String name) { Uri uri = Contenturis.withappendedid (People.content_uri, recNo); Contentvalues values = new Contentvalues (); Values.put (People.name, NAME); Getcontentresolver (). Update (URI, values, NULL, NULL);}Now you can call the above method to update the specified record:UpdateRecord ("XYZ");

If you understand mathematically, you will mistakenly conclude that B and a are the same and should be ' XYZ ', but a

to another string object, the content is "Hello world!", the original object is still in memory, Just s This reference variable no longer points to it.(1) The StringBuffer class, which allows modifications to be generated instead of each different string, is to generate a new object. Also, the conversion of these two kinds of objects is very easy.(2) For string constants, if the content is the same, Java considers them to represent the same string object.

constructor with the keyword new always creates a new object, regardless of whether the content is the same.As for why the string class is designed as an immutable class, it is the purpose of its decision. In fact, not only string, but many classes in the Java Standard Class library are immutable. In the development of a system, we sometimes need to design immutable classes to pass a set of related values, which is the embodiment of object-oriented thinking. Immutable classes have some advantag

name and number in the contact information table in sequence. Modification record:We can use the ContentResolver. update () method to modify the data. Let's write a method to modify the data: private void updateRecord(int recNo, String name) { Uri uri = ContentUris.withAppendedId(People.CONTENT_URI, recNo); ContentValues values = new ContentValues(); values.put(People.NAME, name); getContentResolver().update(uri, values, null, null);} Now you can call the above method to update the

According to JavaScript founder Brandon Eich, the best language constructs for JavaScript are: function is first class citizen (first functions) Closures (closure) Prototypes OBJ = {p1:1, P2: ' ABC '} Array = [+ +] I think that JS's most brilliant idea is to break through the limitations of OOP at that time, to turn object instead of class into a first citizen (Eich's 1,4,5 Three is the manifestation of this idea).C++,java,c# and other languages are in fact class-or
