鍜孋++涓璸arameterized types鐨勪綔鐢ㄧ浉浼?錛堝湪Thinking in java涓瑽ruce Eckel鎻愬埌榪囷級銆?BR>Example: ArrayList<String> stringList = new ArrayList<String>();
......Add elements to the stringList......
String string1 = stringList.get(0);
For-each Loop
浣滅敤錛歩f you need not operate the designated elements within the iterator or array, for-each loop will bring the beautiful code for you and reduce the error opportunities.
eliminates the drudgery and error-proneness of iterators and index variables when iterating over collections and arrays.
Example: String[] stringArray;
for (String individualString: stringArray) {...}
I noticed that most of Russian guys in TopCoder use the for-each loop.
Autoboxing/Unboxing
浣滅敤錛歛utomates to box/unbox between primitive types and the appropriate wrapper types.
Example: ArrayList<Integer> intList = new ArrayList<Integer>();
int total = intList.get(0);
Typesafe Enums
浣滅敤錛歳eplace int Enum Pattern (e.g. public static final int XXX = 0;) to represent a fixed set of constants.
Example: public enum WEEKENDS { SAT, SUN };
private final WEEKENDS weekend;
Varargs
浣滅敤錛歛utomates and hides the passing process in the case of the arbitrary number of parameters;
eliminates the need for manually boxing up argument lists into an array when invoking methods that accept variable-length argument lists.
Varargs can be used only in the final argument position.
Example: public static String format(String pattern, Object... arguments);
Static Import
浣滅敤錛歛void qualifying static members with class names without the shortcomings of the "Constant Interface antipattern."
Once the static members have been imported, we don't have to use "ClassName.staticMemeber" in our classes.
Example: import static java.awt.Math.*;
Metadata
浣滅敤錛歛void writing boilerplate code by enabling tools to generate it from annotations in the source code.
Example: public @interface XXX {...}
