Example
Following is the example to demonstrate how to define a method and how to call it −
public class ExampleMinNumber {
public static void main(String[] args) {
int a = 11;
int b = 6;
int c = minFunction(a, b);
System.out.println("Minimum Value = " + c);
}
/** Returns the minimum of two numbers */
public static int minFunction(int n1, int n2) {
int min;
if (n1 > n2){
min = n2;
} else {
min = n1;
}
return min;
}
}
Output
