In this post, we will see how to solve Cannot find symbol<\/code> in java.<\/p>\n

You will get this error when you have declared something that compiler does not understand. The compiler creates list of identifiers when you compile any program. If compile can not understand any of the identifiers, you will get this error.<\/p>\n

This error generally means the compiler does not recognize any identifier and can not figure out what it means.<\/p>\n

Let’s understand with a very basic example.<\/p>\n

 \npackage org.arpit.java2blog;\n\npublic class CannotFindSymbolMain {\n\n    public static void main(String[] args)\n    {\n        int a = 10;\n        int b = 2;\n\n      division = a\/ b;\n        System.out.println(division);\n    }\n}\n<\/pre>\n
You will get below compilation error.<\/p>\n
\nCannotFindSymbolMain.java:11: error: cannot find symbol
\n            division = a\/ b;
\n  symbol:   variable division
\n  location: class CannotFindSymbolMain
\nCannotFindSymbolMain.java:12: error: cannot find symbol
\n            System.out.println(division);
\n  symbol:   variable division
\n  location: class CannotFindSymbolMain
\n2 errors\n<\/div>\n
Did you understand the issue?<\/strong>
\nWe are getting this error because we did not declare division<\/code> before using it.
\nYou need to change line 11 to:<\/p>\n
 \nint division = a\/ b;\n<\/pre>\n
This will resolve above compilation error.<\/p>\n
There can be multiple reasons for this error.<\/p>\n
    \n
  1. You forgot to declare any variable<\/a><\/li>\n
  2. You misspelled any methodname<\/code>, class<\/a>, variable or interface<\/a>. Please note that java is case sensitive language, so division<\/code> and Division<\/code> will be not be considered same.<\/li>\n
  3. You did not import any class correctly<\/li>\n
  4. You forgot new<\/code> keyword while initializing an object.\n
    \nInteger i = Integer();\n<\/pre>\n
    We forgot to use new<\/code>, so it should be<\/p>\n
    \nInteger i = new Integer();\n<\/pre>\n<\/li>\n
  5. There can be an issue with source file encoding<\/code>. Even though Identifier looks exactly same, but there can hidden characters<\/li>\n<\/ol>\n
    As you can see, there can be multiple reasons for this error. You need to figure out what can be the reason for this error in your program. In most of the cases, this error is due to either the undeclared variable<\/code> or misspelled identifier<\/code>.<\/p>\n","protected":false},"excerpt":{"rendered":"
