Size(String) Method Reference Feedback Definition Namespace: Java.Nio.FileNio.Attributes Assembly: Mono.Android.dll Returns the size of the value of a user-defined attribute. C# Copy [Android.Runtime.Register("size", "(Ljava/lang/String;)I", "GetSize_Ljava_lang_String_Handler:Java...
The size of a String is determined by the number of characters it contains. Each character in Java is represented by two bytes (16 bits) due to the use of the UTF-16 encoding, which allows the representation of a wide range of Unicode characters. Considering the memory constraints, the ma...
The method returns the length which is of type int. So, the String maximum size is the same as the range of integer data type. The maximum length that would be returned by the method would be Integer.MAX_VALUE.The size of int in Java is 4 bytes (included a signed bit, i.e. MSB...

在JDK6及之前版本,字符串常量池是放在Perm Gen区(也就是方法区)中的,StringTable的长度是固定的1009;在JDK7版本中,字符串常量池被移到了堆中,StringTable的长度可以通过-XX:StringTableSize=66666参数指定。至于JDK7为什么把常量池移动到堆上实现,原因可能是由于方法区的内存空间太小且不方便扩展,而堆的内存空间...

However, the method also handles sizes expressed in the following forms: "widthxheight" or "width*height" => new Size(width, height), where width and height are string integers potentially containing a sign, such as "-10", "+7" or "5". text/java 複製 {@code Size.parseSize("3*+...
