For example, consider the following program that reads in an integer from the user:. The issue here is that the program must import java. Scanner or, more generally, java.
Otherwise, the compiler does not know what a Scanner type is. You may encounter a similar error if you forget to import java. Arrays or java.

To fix the code above:. Finally, this error can occur if you have case-sensitive errors with variables. All identifiers in Java are case sensitive. This means that if you declare a variable named average and try to later refer to it using Average , the compiler will complain that it cannot find a symbol named Average. This error occurs when the class name and the filename of a given Java program do not match. For example, say that the following program is saved in a file named Foo.
Since Foo does not match with Bar, the code will not compile. To fix this error, either rename the file or change the class name.

This error is another form of problems with curly braces. Typically this error arises when there are too many curly braces at the end of a program; for example:. One way of figuring out where this error is occurring as with all problems with curly braces is to correctly indent the code. In our example program above, notice that the two curly braces at the end of the program are at the same indentation level, which cannot happen in a valid program. Therefore, simply delete one of the curly braces for the code to compile:.
The error message will tell you which character is missing and on which line. Consider the following program:. These error messages tell you there is a missing curly brace on the first line and a missing semicolon on the seventh line.
Expected identifier, string or number
To fix this kind of error, simply place the missing character in the correct position in the code:. This error occurs when code is written outside of a method; it is typically caused by a mistake in curly braces. In this case, it is somewhat clear that the first print statement must be inside the main method for the code to compile.
There is an extra curly brace in the code above, but the code is not properly indented so it is difficult to see. To fix the error above, simply remove the curly brace at the end of the third line:. Here, there is a missing closing curly brace for the main method. For this error and for many other errors , it may be necessary to look at the lines that come before the error to see where the problem is.
In this case, we simply need to add a curly brace to close the main method on the line before where the compiler issued the warning. After recompiling, all of the errors are resolved. This error occurs when there are type issues with your program.
SOLUTION: SCRIPT Expected identifier, string or number
It is possible to convert between some kinds of types; for example, you can freely convert a char to an int and vice versa, and you can also convert a double to an int with some typecasting. However, you can not convert between primitive types and objects such as String. This is not a syntax error, but rather an error in type logic. It usually does not make sense to try to put a String into an integer type.
Common Java Errors
However, there are some applications where you need to do something like a String to int conversion, such as when the String is a representation of a number:. To fix something like this, you might be able to depend on Java classes such as the Integer class, which is capable of taking a String that represents a number and converting it to an integer type:.

Every method in Java requires that you explicitly state the return type of the method. Even methods that do not return a value must explicitly say void in the method signature, just as the main method does. The only valid indices for an array arr are in the range [0, arr. The error message for this kind of error is similarly irrelevant toward the end of the message. However, the first line lets you know that a problem with an array index was encountered, and the index in error was 3, in this case.
The next line tells you that it encountered this error on line 5 of Test. In this case, the error occurred because the for loop iterates too many times; the value of the loop index, i , reaches 4 and is therefore out of bounds. When dealing with an ArrayIndexOutOfBoundsException , it is usually helpful to print out the value of the index variable that is accessing the array and try to trace through to code to find out why it is reaching that invalid value.

The only valid indices for a String str are in the range [0, str. The error message for this kind of error becomes less relevant towards the end. However, the first line lets you know that a problem with a String index was encountered, and the index in error was Asked 2 years, 9 months ago. Viewed times. I'm getting one issue on Internet Explorer 8 and jQuery 1. Thanks so much. Please question me if you have any questions. Andy Andy 4 3 3 bronze badges. Please show the jQuery statements you have.

Enterprise intranets can use Enterprise Site Mode lists to force IE11 to use lower emulation modes to support legacy non-standards, but you should code new intranet sites to modern standards and allow IE to use the default emulation mode. Adding a site to the Compatibility View list when not using enterprise site mode lists forces IE to use IE7 emulation. Develop for your intranet sites using IE11 and check the Emulation tab of the dev tool for the current Emulation mode aka documentMode that it assumes and how it was determined Enterprise site mode lists, meta x-ua, header x-ua, user CVL.
When debugging in IE11 make sure that you choose the "Always break on exceptions" from the dropdown on the Debug tab, and do not close the dev tool while testing your pages. By default IE will use "Never break on exceptions". IE10 and higher emulation modes ignore conditional comments. Hi all.
It seems jQuery has dropped for IE 8 since version 2. I've tried to use version 1. It's working.
