In array, what happen after for statement we put semicolon? It is does not excute anything or it just ignore the for statement?

Question

For example
System.out.print("Three cheer for Ironman!")
for (int i=0 ; i <4 ; i++);
System.out.println("HIP HIP,HORAY!");

Answer 1

The semicolon ensures that the code that comes after that does not belong to the loop. So the loop does only what is inside the header, in your case i++ until i = 4.

Edit:

for(int i = 0;i<=4;System.out.println(i++));

//prints the numbers from 0 to 4
