Example one:

 Public class INC  {    publicstaticvoid  main (string[] args) {        INC inc=New Inc ();         int i=5;        Inc.fermin (i);        I=i++; // temp=i;i++;i=temp;         System.out.println (i);    }     void Fermin (int  i) {        i+ +;    }}

The result is:
5

Example two: Insert sort, array out of bounds

 Public classinsertsort{ Public Static int[] Sort (int[] intarray) {    intSize=intarray.length;  for(inti=1;i<size;i++){         for(intJ=i;intarray[j]<intarray[j-1] && J > 0;j--)        {            intTemp=intarray[j-1]; Intarray[j-1]=Intarray[j]; INTARRAY[J]=temp; }            }        returnIntarray; }         Public Static voidMain (string[] args) {int[] arr={2,5,7,1,6,11,3,8}; //Insert SortInsertsort.sort (arr);  for(intI:arr)    {System.out.println (i); }            }}

Results:
Java.lang.ArrayIndexOutOfBoundsException

Enter two breakpoints, F6 key debugging.

The revised version is as follows:

 Public classinsertsort{ Public Static int[] Sort (int[] intarray) {    intSize=intarray.length;  for(inti=1;i<size;i++){         for(intJ=i; J > 1&&intarray[j]<intarray[j-1];j--)        {            intTemp=intarray[j-1]; Intarray[j-1]=Intarray[j]; INTARRAY[J]=temp; }            }        returnIntarray; }         Public Static voidMain (string[] args) {int[] arr={2,5,7,1,6,11,3,8}; //Insert SortInsertsort.sort (arr);  for(intI:arr)    {System.out.println (i); }            }}

A sort from small to large.
