There are some C# keywords that can be used in Java as variable, field, parameter and so on. These identifiers should be renamed to something else.

Some of frequently used ones are: in, out, params, base, string, object. To rename them, we append an underscore character ('_') at the beginning of them.

[Java]

public class A 
{ 
    public void Method(String string)
    {
        int in;
        int out; 
        out = in.toInt();
    } 
}

[C#]

public class A 
{ 
    public void Method(String _string)
    {
        int _in;
        int _out; 
        _out = _in.toInt();
    } 
}
