Java Matrix Enum class [duplicate]

I'm trying to make an arkanoid game and I created an enum class that holds all the levels of the game.I assigned to each block a char('y' for yellow,etc...) but I have a few errors:

package main;

public enum Level{ //ERROR Syntax error on token '{',@ expected after this token
    Level1 ( {{'g','g','g','g','g'},
              {'y','y','y','y','y'},
              {'b','b','b','b','b'},
              {'r','r','r','r','r'},
              {'m','m','m','m','m'}} ) //ERROR Syntax error, insert "Identifier" to complete EnumConstant
    ;

    private final char[][] levelCode;

    private Level(char[][] levelCode){
        this.levelCode=levelCode;
    }       
}
