What is type promotion of java?
Type PromotionIn the aforementioned example System.out.println(3 + 4), the expression 3 + 4 is evaluated to 7 and then converted automatically, at runtime, to a String value which is whatprintln expects. This automatic conversion is a somewhat special case of type promotion. Type promotion is an automatic type conversion from a "lesser" base type to a "greater" one or from any type to String via the toString() method.A promotion from on base type to another may occur in an arithmetic expression:Example:double x = 3.14 + 10; /* 10 is promoted to a double */ double y = 12; /* 12 is promoted to a double then assigned */ As mentioned earlier, type promotion occurs from a "lesser" type to a "greater" one where a type is "less" than another if it offers smaller precision. In our previous example, an int offers less precision than a double thus an int value can be promoted to a double as necessary. For the same reason a double cannot be promoted to an int. If an double is used where an int is expected, Java will generate an error:Example:int z = 2.4; Compile-time error: possible loss of precision
What is the difference between Java 1.6 and Java 1.7?
Java 1.7 supports the features of 1.6 but introduces some new conventions:- Java 7 allows use of String object in the expression of a switch statement.- Auto-closing of resources (also known as try-with-resources)- Allow catching of multiple Exceptions- Allows underscores in Numeric Literal for readability (e.g. 1_234_567_890_123_456L)- Substitute the parameterized type of the constructor with an empty set of type parameters ()For full list see Java Programming Language Enhancements.
What is gini in Java language?

Is button a data type in Java?
In Java, just about anything is defined as a class; a class is a data type, so yes.
What happens when you perform arithmetic operations mixing different types of variables in java programming?
Java performs an implicit conversion to a unifying type.
What is the difference between automatic type conversion and explicit type conversion?
In programing languages automatic type conversion occurs when the language automatically changes a variable between different types for you. For example changing a number type to a string type. It usually does this because the type you are using is incompatible with the operation you are trying to preform, so it converts it to a new type which is compatible for you. Explicit conversion requires that you, the programmer, explicitly code the details on how the conversion is to take place. While automatic type conversion is convenient the conversion may not perform exactly how you expect. For example converting between a floating point number , e.g. 3.5 to an integer - will the system round the floating point number to 4 , or will it truncate the number to 3?

What is implicit and explicit data type conversion in C programming?
explicit type conversion is done by compile automatically for example: int x; float y=10.4545 // to convert the value of float into int type we use x=y; //automatic conversion while if we force to convert one data type to another then it is called implicit for example: int x; float y=10.4545 // to convert the value of float into int type we use x= (int)y; //forced conversion
