int cannot be converted to string?
提问by Vestel
I am trying to write the instructions to notice when circle is about to be 12 and then add 1 to square.
我正在尝试编写说明以注意圆何时将变为 12，然后将 1 添加到正方形。
The code below works fine for me
下面的代码对我来说很好用
int x = Integer.parseInt(circle.getText());
x = x + 1;
String z = Integer.toString(x);
circle.setText(z);
However, I am having trouble with these new instructions I am trying to write. How can I get square, convert to integer, add 1 and then put the value back?
但是，我在尝试编写这些新指令时遇到了麻烦。我怎样才能得到平方，转换为整数，加1然后把值放回去？
int q = Integer.parseInt(square.getText());
x = q + 1;
square.setText(x);

You can convert to Stringusing Integer.toString():
您可以转换为String使用Integer.toString()：
square.setText(Integer.toString(x));

Why would an intbe convertible to a String(unless an implicit conversion exists, which is not the case, there is not a lot of implicit things with the Java compiler, primitive wrappers and string concatenation apart) ?
为什么 aint可以转换为 a String（除非存在隐式转换，事实并非如此，Java 编译器、原始包装器和字符串连接并没有很多隐式的东西）？
Use one of these two options :
使用以下两个选项之一：
square.setText(String.valueOf(x));
square.setText(x + "");

square.setText(x+"")
