What are block lambda expressions in Java?
A lambda block states that lambda expression with multiple statements. It expands the type of operations to perform with a lambda expression. The multiple statements containing bodies are called expression bodies. A lambda expression with expression bodies is called expression lambdas. Whenever we are using expression lambdas, explicitly use a return statement to return a value.
Example
interface NumberFinder {
int finder(int number1, int number2);
}
public class LambdaNumberFinder {
public static void main(String args[]) {
NumberFinder numberFinder = (number1, number2) -> {
int temp = 0;
if(number1 > number2) {
temp = number1;
} else {
temp = number2;
}
return temp; // explicitly return a value
};
System.out.println("The valus is : " + numberFinder.finder(10, 5));
}
}Output
The valus is: 10
