Type inference and target type

Could you explain if there is any difference between type inference and type targetting or type targeting is just type inference? Thanks.

I'm not sure what you mean by "type targetting", but "target type" is a thing. From the Java tutorial on type inference:

The target type of an expression is the data type that the Java compiler expects depending on where the expression appears

For instance, in the statement int a = b;, the target type is int - the expression, b, should have a type of int (or something convertible to it), because its context requires that.

"Type inference" by contrast is a process used to determine the type of an expression. The target type may be used as part of the type inference process.
