Autobox unbox occurs inside expressions.

 

public class AutoBox3 { 
  public static void main(String args[]) { 
     
    Integer iOb, iOb2; 
    int i; 
 
    iOb = 100; 
    System.out.println("Original value of iOb: " + iOb); 
 
    // The following automatically unboxes iOb, performs the increment, and then reboxes 
    // the result back into iOb. 
    ++iOb; 
    System.out.println("After ++iOb: " + iOb); 
 
    // Here, iOb is unboxed, the expression is evaluated, and the result is reboxed and 
    // assigned to iOb2. 
    iOb2 = iOb + (iOb / 3); 
    System.out.println("iOb2 after expression: " + iOb2); 
 
    // The same expression is evaluated, but the result is not reboxed. 
    i = iOb + (iOb / 3); 
    System.out.println("i after expression: " + i); 
 
  } 
}
