java declare interface code example
Example 1: java implement interface
// Assume we have the simple interface:
interface Appendable {
void append(string content);
}
// We can implement it like that:
class SimplePrinter implements Appendable {
public void append(string content) {
System.out.println(content);
}
}
// ... and maybe like that:
class FileWriter implements Appendable {
public void append(string content) {
// Appends content into a file
}
}
// Both classes are Appendable.
Example 2: how to implement a interface in java
interface methods{
public static hey();
}
class scratch implements methods{
// Required to implement all methods declared in an interface
// Or else the class becomes abstract
public static hey(){
System.out.println("Hey");
}
}
