使用==为什么2个字符不相等？

Question

为什么此代码块返回false ...

string

...当此代码块返回true时？

char ra1= '\u30E9';
char ra2= '\u30E9';
Character RA1= ra1;
Character RA2= ra2;
System.out.println("Does Character RA1 == Character RA2? " + (RA1 == RA2)); //returns false

他们似乎对我做了同样的事情，并且char a1= 'a'; char a2= 'a'; Character A1= a1; Character A2= a2; System.out.println("Does Character A1 == Character A2? " + (A1 == A2)); //returns true 都保持相同的Characters值，所以我不明白为什么char会返回{ {1}}为{1}}为==为
