本文介绍了您可以将char与==进行比较吗?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
对于字符串,您必须使用equals进行比较,因为==仅比较引用。
For Strings you have to use equals to compare them, because == only compares the references.
如果我将char与==比较,它是否可以提供预期的结果?
Does it give the expected result if I compare chars with == ?
我在stackoverflow上也看到过类似的问题,例如
I have seen similar questions on stackoverflow, E.g.
- What is the difference between == vs equals() in Java?
但是,我还没有看到有人问过要使用==字符。
However, I haven't seen one that asks about using == on chars.
推荐答案
是的,字符
与其他任何原始类型一样,您可以通过 ==
进行比较。
Yes, char
is just like any other primitive type, you can just compare them by ==
.
您甚至可以直接将char与数字进行比较并将其用于计算例如:
You can even compare char directly to numbers and use them in calculations eg:
public class Test {
public static void main(String[] args) {
System.out.println((int) 'a'); // cast char to int
System.out.println('a' == 97); // char is automatically promoted to int
System.out.println('a' + 1); // char is automatically promoted to int
System.out.println((char) 98); // cast int to char
}
}
将打印:
97
true
98
b
