Please give the program, function to get "a piece of program code" run length

One day I saw a few Java topics, I wrote a bit, nonsense less, directly on the code

3. Known int array arr[t],

Please: ① print the array. The output format is: [Arr1,arr2,arr3,...].

② the maximum value of the output array, max and Min.

③ uses the bubbling sort to sort the array and prints the sorted arrays.

4. Please give the program, function to get "a piece of program code" run time. Requirements:

The ① program framework is defined in the parent class.

② "A piece of program code" is given in the subclass and overrides the corresponding method in the parent class.

③ "Part of the program code" is: Print a "*" composed of graphics, see Figure 1.

Figure 1

Question three:

 Public classTestarr { Public Static voidMain (string[] arg) {int[] arr = {23,12,3,45,25,46,75,15,12,52}; System.out.println ("Print Array:"); System.out.print ("[");  for(inti=0;i<arr.length;i++) {System.out.print (Arr[i]+", "); } System.out.print ("]"); System.out.println ("\ n" + "Maximum value:" +Getmax (arr)); System.out.println ("Minimum value:" +getmin (arr));    Arrsort (arr); }     Public Static intGetmax (int[] arr) {          intMax =Integer.min_value;  for(inti = 0; i < arr.length; i++) {              if(Arr[i] >max) Max=Arr[i]; }          returnMax; }       Public Static intGetmin (int[] arr) {          intMin =Integer.max_value;  for(inti = 0; i < arr.length; i++) {              if(Arr[i] <min) min=Arr[i]; }          returnmin; }       Public Static intArrsort (int[] arr) {                   for(inti=arr.length-1;i>=0;i--){             for(intj=0;j<i;j++){                if(arr[j]>arr[j+1]){                    inttemp =Arr[j]; ARR[J]= Arr[j+1]; Arr[j+1] =temp; }}} System.out.println ("Bubble sort thick Result:"); System.out.print ("[");  for(inti=0;i<arr.length;i++) {System.out.print (Arr[i]+", "); } System.out.print ("]"); return0; }  }
Operation Result:

Question Fourth:

 Public classdiamond{ Public Static voidMain (string[] args) {LongStarttime=System.currenttimemillis ();   Onecode (); LongEndtime=System.currenttimemillis (); System.out.print ("\ n" + "program Run Time:" + (Endtime-starttime) + "MS"); }  Public Static voidOnecode () { for(inti=1;i<5;i++){     for(intj=1;j<i+4;j++){         for(intt=0;t<i;t++){            if(j== (5-i+2*t)) {System.out.print ("*"); }} System.out.print (" "); } System.out.print ("\ n"); }}}
