variable access outside of if statement

Question

I am trying to access variable outside an if statement in java. The variable is axeMinDmg. Here is what i have but getting an error. I want minDmg = axeMi

Answer 1

Just declare the integer outside the if statement:

 int minDmg;
 if(weapon.equals("axe")){
     minDmg = axeMinDmg;
 } else {
     System.out.println();
 System.out.println("Can access variable: " + minDmg);

Answer 2

You'll need to define the variable outside of the if statement to be able to use it outside.

Answer 3

In Java, variables are defined within a scope. Here the scope is the if block. so if you declare it outside the if block, it will be available in the enclosing method scope.

Answer 4

If you want to assign a variable to outside of if-else block, you can use ternary operator which represented by the : operator.

For example, the standard if-else Java expression:

int money;
if (shouldReceiveBonus()) {
    price = 100;
}
else {
    price = 50;
}

With ternary operator is equivalent to:

int money = shouldReceiveBonus() ? 100 : 50;
