Quick Answer: Can you return in an if statement Java?

Can we use return in if statement Java?

A return statement stops the execution of the method right there, and returns its value. In fact, if there is code after a return that the compiler knows it won’t reach because of the return , it will complain. You don’t need to use a variable outside the if to return it at the end.

Can we use return in if else statement?

Every return statement is inside an if statement. While it may be logically impossible as written, the compiler needs a return for when none of the if evaluate true.

Can we write return statement in if block?

Yes it is possible.

Why we use return in if statement?

A return statement ends the execution of a function, and returns control to the calling function. Execution resumes in the calling function at the point immediately following the call. A return statement can return a value to the calling function.

Can you return a for loop?

It is good practice to always have a return statement after the for/while loop in case the return statement inside the for/while loop is never executed. Otherwise, a compile-time error will occur because the method cannot return nothing (unless it has the Java reserved word “void” in the method header).

In Java, return is a reserved keyword i.e, we can’t use it as an identifier. It is used to exit from a method, with or without a value.

Should I use else or return?

Don’t put an else right after a return. Delete the else, it’s unnecessary and increases indentation level. (I’m not exaggerating, see this comment and this comment from Mozilla’s VP of Engineering and CTO respectively, about an example very similar to this.)

What is the return type of IF statement?

if (cond) { expr } returns common base type of Unit and type of expr , just like if (cond) { expr } else { () } . As always, an if statement evaluates a logical condition and has to return a logical result.

How do you end an if else?

In the multiline syntax, the If statement must be the only statement on the first line. The ElseIf , Else , and End If statements can be preceded only by a line label. The If … Then … Else block must end with an End If statement.

What will be returned if f AB is called?

Why do we use return 0 in C programming?

The main function is generally supposed to return a value and after it returns something it finishes execution. The return 0 means success and returning a non-zero number means failure. Thus we “return 0” at the end of main function.
