Java7带来的新的语言特性

http://www.iteye.com/topic/1111973

1。二进制字面量值

// An 8-bit 'byte' value:

Java代码

byte aByte = ( byte )0b00100001;

// A 16-bit 'short' value:

short aShort = ( short )0b1010000101000101;

// Some 32-bit 'int' values:

int anInt1 = 0b10100001010001011010000101000101;

int anInt2 = 0b101;

int anInt3 = 0B101; // The B can be upper or lower case.

// A 64-bit 'long' value. Note the "L" suffix:

long aLong = 0b1010000101000101101000010100010110100001010001011010000101000101L;

2.可以在数字字面量中使用"下划线"("_")

Java代码

long creditCardNumber = 1234_5678_9012_3456L;

long socialSecurityNumber = 999_99_9999L;

float pi = 3 .14_15F;

long hexBytes = 0xFF_EC_DE_5E;

long hexWords = 0xCAFE_BABE;

long maxLong = 0x7fff_ffff_ffff_ffffL;

byte nybbles = 0b0010_0101;

long bytes = 0b11010010_01101001_10010100_10010010;

要注意的是，下划线放在以下几个地方是不正确的：

(1).最前面; 如_52 ，这不是数字字面量，而是也是变量名了

(2).小数点的两边; 如float pi1 = 3_.1415F 和 float pi1 = 3._1415F 都是不正确的

(3).最后面; 如int x3 = 52_;

(4).不能放在0x这样前缀的中间，如：int x5 = 0_x52;

3.可以在switch语句中使用String类型的变量

Java代码

public String getTypeOfDayWithSwitchStatement(String dayOfWeekArg) {

String typeOfDay;

switch (dayOfWeekArg) {

case "Monday" :

typeOfDay = "Start of work week" ;

break ;

case "Tuesday" :

case "Wednesday" :

case "Thursday" :

typeOfDay = "Midweek" ;

break ;

case "Friday" :

typeOfDay = "End of work week" ;

break ;

case "Saturday" :

case "Sunday" :

typeOfDay = "Weekend" ;

break ;

default :

throw new IllegalArgumentException( "Invalid day of the week: " + dayOfWeekArg);

}

return typeOfDay;

}

4.类型推断，泛型构造器和非泛型的Classes

(Type Inference and Generic Constructors of Generic and Non-Generic Classes)

首先看一个泛型构造器和类型推断的例子：

Java代码

class MyClass<X> {

<T> MyClass(T t) {

// ...

}

}

这里X是泛型类MyClass<X>的参数化类型，而T是其构造器的参数化类型。

那怎么样实例化它呢？

new MyClass<Integer>("")，这条语句创建了MyClass<Integer>一个实例，这条语句显式的指定了MyClass<X> 中的参数X的类型为Integer。同时，因为实际调用构造器时参数是String类型，所以编译器推断String就是这个T的类型,。

接下来看下面这两种例子：

1.MyClass<Integer> myObject = new MyClass<>("");

在这里例子中，编译器推断Integer为泛型类MyClass<X>正式参数化类型X的类型，推断String为该泛型类构造器的正式参数化类型T的实际类型。

2.MyClass<Integer> myObject = new <String> MyClass<>("");

在这里例子中，编译器推断Integer为泛型类MyClass<X>真是参数化类型X的类型，同时这条语句显式的指定了构造器的正式参数化类型T的实际类型。

5. Improved Compiler Warnings and Errors When Using Non-Reifiable Formal Parameters with Varargs Methods不知道怎么翻译。 “当在可变长参数方法中使用不可具体化的参数时改良的警告和错误”，行么？

6.带有资源的try语句

The try-with-resources Statement

一个带有资源的try语句就是一个声明了一个或者多个资源的 try语句，资源是指当程序结束后必须关闭的对象。带有资源的try语句保证在语句结束的时候每个资源都会被关闭(调用其close()方法)。任何实现了java.lang.AutoCloseable 或者 java.io.Closeable接口的对象都可以被用作为一个资源。

下面这个例子的作用是从一个文件中读取第一行。使用了一个BufferedReader从文件中读取数据，在这里BufferedReader就是一个在程序结束后必须关闭的资源。

Java代码

static String readFirstLineFromFile(String path) throws IOException {

try (BufferedReader br = new BufferedReader( new FileReader(path))) {

return br.readLine();

}

}

上面说到可以在try语句中声明一个或多个资源，下面就是一个声明了多个资源的try语句，它的功能是获得打包在zip文件中的所有文件的文件名，然后把这些文件名保存到一个txt文件中。

Java代码

public static void writeToFileZipFileContents(String zipFileName, String outputFileName)

throws java.io.IOException {

java.nio.charset.Charset charset = java.nio.charset.Charset.forName("US-ASCII" );

java.nio.file.Path outputFilePath = java.nio.file.Paths.get(outputFileName);

// Open zip file and create output file with try-with-resources statement

try (

java.util.zip.ZipFile zf = new java.util.zip.ZipFile(zipFileName);

java.io.BufferedWriter writer = java.nio.file.Files.newBufferedWriter(outputFilePath, charset)

// Enumerate each entry

for (java.util.Enumeration entries = zf.entries(); entries.hasMoreElements();) {

// Get the entry name and write it to the output file

String newLine = System.getProperty("line.separator" );

String zipEntryName = ((java.util.zip.ZipEntry)entries.nextElement()).getName() + newLine;

writer.write(zipEntryName, 0 , zipEntryName.length());

}

}

}

大家需要知道的是，一个带有资源的try语句和普通的try语句一样可以有catch和finally语句块，但是任何catch或者finally块都是在所有的资源关闭后才执行的。

7.捕捉复合（Multiple）异常类型以及使用改良的类型检查重掷（Rethrowing）异常

在Java6以及以前版本一般我们这样捕获多个类型的异常：

Java代码

catch (IOException ex) {

logger.log(ex);

throw ex;

catch (SQLException ex) {

logger.log(ex);

throw ex;

}

在Java7里可以这么干：

Java代码

catch (IOException|SQLException ex) {

logger.log(ex);

throw ex;

}

下面看一个抛出异常的例子：

JDK6及以前版本:

Java代码

static class FirstException extends Exception { }

static class SecondException extends Exception { }

public void rethrowException(String exceptionName) throws Exception {

try {

if (exceptionName.equals( "First" )) {

throw new FirstException();

} else {

throw new SecondException();

}

} catch (Exception e) {

throw e;

}

}

JDK7:

Java代码

public void rethrowException(String exceptionName)

throws FirstException, SecondException {

try {

// ...

}

catch (Exception e) {

throw e;

}

}

Java7异常新特性之mutilcatch

http://c-zhiwu.iteye.com/blog/975253

Java7增强了Java的异常处理机制，主要表现为三个方面：捕捉多种异常类型（multicatch）；重新抛出(rethrow)异常；简化资源清理（try-with-resources）

捕捉多种异常类型

从Java7开始，你就可以在一个catch块中捕捉多种类型的异常了。增加multicatch的特性的主要是为了降低重复代码和较少过大范围的异常捕捉(例如这样的捕捉 catch（Exception e）)。

假如你正开发这样一个应用程序，这个程序可以灵活地将数据复制到数据库或者文件中，清单1（CopyToDatabaseOrFile.java）模拟了这种程序，展示了在catch模块中存在重复代码的现象：

Java代码

// CopyToDatabaseOrFile.java

import java.io.IOException;

import java.sql.SQLException;

public class CopyToDatabaseOrFile {

public static void main(String[] args) {

try {

copy();

} catch (IOException ex) {

System.out.println(ex.getMessage()); // additional handler code

} catch (SQLException ex) {

System.out.println(ex.getMessage()); // additional handler code that's identical to the previous handler's // code

}

}

static void copy() throws IOException, SQLException {

if (Math.random() < 0.5 )

throw new IOException( "cannot copy to file" );

else

throw new SQLException( "cannot copy to database" );

}

}

清单1： CopyToDatabaseOrFile.java

Java7克服了这种代码重复的问题。你只需在一个catch块中指定多个需要处理的异常，将这些异常按顺序排列，并用“|”分隔每个异常。如：

Java代码

try {

copy();

}catch (IOException | SQLException ex){

System.out.println(ex.getMessage());

}

现在，当copy（）方法抛出任何一种类型，都会在catch块中被捕捉。

当在catch中声明多种异常时，被声明的异常默认为final的，也就是说不能再修改异常的引用。如上例中，不能再将ex赋值给另外一个异常（如ex=new MyException()）。
