The presentation gives an overview about some interesting Java 7 features:

Java Programming Language Changes Highlights (project Coin)


 //Binary Literals
****package java7;
public class BinaryLiterals {
byte b = 0b01001001;
short s = 0B00100100;
int x = 0b10010010;
long y = 0B01001001;
Underscores in Numeric Literals
//Underscores in Numeric Literals
package java7;
public class UnderscoresInNumericLiterals {
short answer = 0b1_0_1_0_1_0;
int twoMonkeys = 0xAFFE_AFFE;
long smallestLong = 0x8000_0000_0000_0000L;
long somePhoneNumber = +49_7031_4357_0L;
double e = 2.718_281_829D;
// before java 7 underscores not allows in numeric literals
Strings in switch Statements
 //Strings in switch Statements
package java7;
public class StringsInSwitch {
public static void main(String[] args) {
String os = System.getProperty("");
// NB: if the string in switch is null, we will see NPE on the next line!
switch (os) {
case "Linux":
case "Windows":
System.out.println("Not so cool!");
//Before JDK 7, only integral types can be used as selector for switch-case statement.
//In JDK 7, you can use a String object as the selector. 
The try-with-resources Statement

Before Java 7

Resources are need to be closed manually. After processing.

In Java 7

It implements autoclosable method.

Close method run automatically.

Need not to close the resources manually.
