java-7

In Java 6, System.out.println(String.valueOf('\u0130').toLowerCase()); prints i ( u0069 ), but in Java 7 it prints i with double dots ( u0069 u0307 ). I understand it is a Turkish character, but how do I make Java 7 print the same output as v6 using this code? System.out.println(inputText.toLowerCase()); Also make sure that the code can handle international text without hardcoding the toLowerCase function to use only Turkish locale. There is a quite detailed blog post about this i toLowerCase problem Let me try to summarize the essential parts: In Java 7 this method has indeed changed and

I created two java files: Pizza.Java and PizzaOrder.Java . I tried compiling my code using javac in the command prompt like this: javac pizzaorder.java I am getting access is denied error: C:\Users\Meutex>cd\ C:\>cd "Program Files\Java\jdk1.7.0\bin" C:\Program Files\Java\jdk1.7.0\bin>javac PizzaOrder.java PizzaOrder.java:23: error: cannot find symbol Pizza order = new Pizza (); ^ symbol: class Pizza location: class PizzaOrder PizzaOrder.java:23: error: cannot find symbol Pizza order = new Pizza (); ^ symbol: class Pizza location: class PizzaOrder 2 errors C:\Program Files\Java\jdk1.7.0\bin

Im using Files.WalkFileTree() to navigate folder and counting audio files, but there is a problem when it encounters a tar file, it seems to be treating it as an actual folder I was expecting it to just skip over it. I cannot see any options that let me control this behaviour Code: package com.jthink.songkong.fileloader; import com.jthink.songkong.cmdline.SongKong; import com.jthink.songkong.ui.MainWindow; import java.nio.file.*; import java.nio.file.attribute.BasicFileAttributes; import java.util.concurrent.Callable; import java.util.logging.Level; /** * Count the number of files that can be

public List<String> foo1() { List<String> retval = bar(); if (retval == null) return Collections.emptyList(); else return retval; } public List<String> foo2() { List<String> retval = bar(); return retval == null ? Collections.emptyList() : retval; } Why does foo1() compiles fine whereas foo2() has an error? (to be more precise "Type mismatch: cannot convert from List<capture#1-of ? extends Object> to List<String>" ) I would have thought that both functions would compile to the same bytecode, so a clever compiler should infer the correct type for emptyList() ... Compiles for me fine in java 8.

Java 7 on 32-bit Windows 7 - Java Webstart - Unable to load resource I can't launch any java webstart application on a 32-bit Windows 7 system. E.g. ArgoUML - http://argouml-downloads.tigris.org/jws/argouml-latest-stable.jnlp Everything works fine with Java 6, but with Java 7 I get this kind of errors: Unable to load resource: java.io.IOException: Error writing to server or java.net.SocketException: Connection reset Java version: Java Web Start 10.7.2.11 Using JRE version 1.7.0_07-b11 Java HotSpot(TM) Client VM Here is the trace log: Log started: pe, 21 syys 2012 21:04:19 +0300 basic: Java

I have some file I/0 traversal code written in Java 6, trying to move it the New I/O in Java 7 but I cannot find any replacement for this kind of stuff. File[] files = dir.listFiles(AudioFileFilter.getInstance()); Namely, no way to filter paths only files, and it returns list of files so I would then have to convert each file to path (file.toPath) if I wanted to limit the use of File in methods it calls, which seems rather laborious. I did look at FileVisitor but this does not seem to allow you to control how the the tree is traversed so I don' think it will work for me. So how much of a
