代码示例来源：origin: stackoverflow.com

// These two have the same value
new String("test").equals("test") // --> true 
// ... but they are not the same object
new String("test") == "test" // --> false 
// ... neither are these
new String("test") == new String("test") // --> false 
// ... but these are because literals are interned by 
// the compiler and thus refer to the same object
"test" == "test" // --> true 
// ... but you should really just call Objects.equals()
Objects.equals("test", new String("test")) // --> true
Objects.equals(null, "test") // --> false
