The following program causes JDK1.0 compiler to give a compiler error.

Note the typo in the type of the declaration of DIFFERENT.


---------------------------------------------
import java.io.IOException;

class Status {
    Status(String s) {
    }
}

class bug {
    public Status compare(int a, int[] b) {
for (int i = 0; i < b.length; i++) {
try {
boolean same = compare(a, b[i]);
return (same ? SAME : DIFFERENT);
}
catch (IOException e) {
return ERROR;
}
}
return NOT_FOUND;
    }

    public boolean compare(int a, int b) throws IOException {
return (a == b);
    }

     private static final Status SAME = new Status("same");
     private static final tatus DIFFERENT = new Status("different");
     private static final Status ERROR = new Status("error");
     private static final Status NOT_FOUND = new Status("not found");
}
