- After the Simple Codes, then go to complex Codes that are very important.
1. Print Hello World on console
public class FirstOne{
public static void main(String args[]){
System.out.println("Hello World”);
}
}
2. Pre-fix and Post-fix Operators
public class IncrementExample{
public static void main(String args[]){
int x=10;
int y;
y = x++;
System.out.println(x +" "+y);
y = x++;
System.out.println(x +" "+y);
}
}
The answer comes as:
x=11, y=10.
x = 12, y = 12
Process 1: Process 2:
y=10++; y =11++;
y = 10; y = 12;
x = 11; x = 12;
