Invalid escape character
The compiler detected the use of an invalid escape character. This error usually occurs when a syntactical error is found in a Unicode escape sequence. The error can also occur if you use a "\" character in a string assignment.
The following example illustrates this error:
public class Simple {
int i = \u032;
// error: Unicode uses 4 hex digits
int x = \u0032;
//correct assignment of a Unicode escape sequence
}
The following example illustrates the error being caused by assigning the "\" character improperly to a string:
public class Simple{
public String str = "C:\Windows\Desktop";
//error: invalid assignment of the '\' character to a string
//To assign it correctly use the '\\' character assignment
}
