如何比较Java中的字符串? 23个答案

String TypedMaxNumber = MaxValue.getText();
if(TypedMaxNumber == "100")
    System.out.println(TypedMaxNumber+" = 100");

I think it is a silly problem, but when I am running to run this program and I type 100 in the text Field it is not going inside the loop. What could be the reason.

我认为这是一个愚蠢的问题,但是当我运行这个程序并在文本字段中输入100时,它不会进入循环。可能是什么原因。

I am running to run this program and I type 100 in the text Field it is not going inside the loop.

我正在运行这个程序,我在文本字段中输入100,它不会进入循环内部。

Its

if(TypedMaxNumber.equals("100"))

Since TypedMaxNumber is of type String. equals() check for value equality

由于TypedMaxNumber的类型为String。 equals()检查值的相等性
