What are the exam questions for companies recruiting Java programmers?

I personally feel that academic qualifications are not important, especially as a programmer. I am also a Java programmer. The interview questions at that time were set by the company itself. There were three questions. The first question was: "Database" "Question", every programmer must have considerable understanding and understanding of the database, and must also be proficient in its application. The second question is: "java question", which mainly writes the operation results. The main purpose of this question is: to understand the java code Familiarity assessment, the third question: "java programming", for java programmers, programming ability is indispensable, this question mainly tests the applicant's comprehensive programming ability, the above is just my personal interview situation, I hope It can help you! Java programmers, if they have no work experience, will not have much money at the beginning, only around 2000, but experience will be gained, and they will gradually increase in the future. Depending on your ability, the amount of ability will determine what you can get. What a salary!
