答:可以使用==操作符来比较两个String对象的引用是否相等,例如:String s1 = "Hello"; String s2 = "Hello"; s1 == s2。 12.问:如何判断一个字符串是否包含另一个字符串? 答:可以使用contains()方法来判断一个字符串是否包含另一个字符串,例如:String str = ...

then the JAR files can be enumerated explicitly in the class path. Expansion of wild cards is done early, before the invocation of a program’s main method, rather than late, during the class-loading process. Each element of the input class path that contains a wildcard is replaced by the...
