java: cannot infer type for local variable, cannot use var on variable without initializer

java: cannot infer type for local variable myVar

If you get a Compile-Time Error "cannot infer type for local variable" in your Java code, then surely you are using JDK 10 or above and you are using var - local variable type inference in your program,

You will get the inferred type for local variable error when you declare a var local variable but do not initialize it. You need to make sure that you do declaration and initialize together,

java: cannot infer type for local variable myVar
  (cannot use 'var' on variable without initializer)

As said before, you need to initialize the var variable,

    public void myMethod() {
       var myVar = "";
        System.out.println(myVar);
    }
