int i = 22; String stringValue = String.valueOf(i); System.out.println("String value: " + stringValue); 基本数据类型转成字符串表示形式时,可以使用String.valueOf(xx),但不能直接使用 xx.toString()方法(基本数据类型不具备方法和属性),也不能通过

The default allocators supplied with container classes are sufficient for most programming needs. Writing and using your own allocator class is an advanced C++ feature. Example C++ Copy // basic_string_get_allocator.cpp // compile with: /EHsc #include <string> #include <iostream> int main( ...
intlen, TRAPS) { unsignedinthashValue = java_lang_String::hash_string(name, len); intindex = the_table()->hash_to_index(hashValue); oop string = the_table()->lookup(index, name, len, hashValue); // Found if(string != NULL)returnstring; // Otherwise, add to symbol to table re...
The implementation of string conversion is typically through the method toString, defined by Object and inherited by all classes in Java. Since: 1.0 See Also: Object.toString(), StringBuffer, StringBuilder, Charset, Serialized Form See The Java™ Language Specification: 15.18.1 String Concatenation...
2. 使用Wrapping Classes 有时,我们需要手动将String转换为其他对象。例如,将String转换为Integer对象。可以通过包装类实现这一点。 publicclassStringToInteger{publicstaticvoidmain(String[]args){StringnumberStr="123";ObjectnumberObj=Integer.valueOf(numberStr);// String转换为Integer,再转为ObjectSystem.out.prin...
All Known Implementing Classes: CharBuffer, Segment, String, StringBuffer, StringBuilder Method: char charAt(int index); //返回索引处的字符char static int compare(CharSequence cs1, CharSequence cs2); //按照字典顺序比较两个字符串 default boolean isEmpty(); //是否为空 int length(); //返回长度...
Console.WriteLine(string.Concat(o)); } } // Create two empty test classes. class Test1 { } class Test2 { } // The example displays the following output: // Test116Test2Demonstration 注解 该方法通过调用该对象的无参数 ToString 方法连接 args 中的每个对象;它不添加任何分隔符。 String.Empty ...
