99 exponentiation Table/array sort/Reverse output string

Hello everyone:

Today, when visiting Baidu, a Sesame asked a question, feeling he is a beginner! Embellish his code into the next few programs! Let's share it!

A total of five methods:

<span style= "FONT-SIZE:18PX;" >//Format 4 * 3 * 2 * 1 = 24</span>

<span style= "FONT-SIZE:18PX;" >//</span><span style= "FONT-SIZE:18PX; Font-family:arial, Helvetica, Sans-serif; > number from zero to nine added to 13 </span>

<span style= "FONT-SIZE:18PX;" >//</span><span style= "FONT-SIZE:18PX; Font-family:arial, Helvetica, Sans-serif; > 99-Exponent Table </span>

<span style= "FONT-SIZE:18PX;" >//</span><span style= "FONT-SIZE:18PX; Font-family:arial, Helvetica, Sans-serif; > Array Sorting </span>

<span style= "FONT-SIZE:18PX;" >//</span><span style= "FONT-SIZE:18PX; Font-family:arial, Helvetica, Sans-serif; > Reverse Output string </span>

I have integrated these methods, console input and output printing!

<span style= "font-size:18px;" >import Java.util.scanner;public class Test {public static void main (string[] args) {Scanner inrecurrence =new Scanner ( system.in); System.out.println ("Please enter the number of starts you need to calculate the score, enter end:"); Long n = Recurrence (Inrecurrence.nextint ()); SYSTEM.OUT.PRINTLN (n); getforstring ();p rintstring (); Scanner Inshuzu =new Scanner (system.in); int[] Shuzu=new int[3];     System.out.println ("Please enter a 3 number comparison"); for (int i=0;i<shuzu.length;i++) {shuzu[i]=inshuzu.nextint ();} Compute (Shuzu); Scanner Zifuchuan =new Scanner (system.in); System.out.println ("Enter string for reverse output"); GetString (Zifuchuan.nextline ());} Format 4 * 3 * 2 * 1 = 24private static long recurrence (int n) {if (n = = 1) {System.out.print ("1 ="); return 1;} Else{system.out.print (n+ "*"); return n * Recurrence (n-1);}} </span> 

<span style= "font-size:18px;" >//</span><span style= "FONT-SIZE:18PX; Font-family:arial, Helvetica, Sans-serif; > The number </span><span style= "font-size:18px" from zero to nine added to 13; >private static void Getforstring () {SYSTEM.OUT.PRINTLN (the number added from zero to nine is 13: "), for (int a=0; a<=9; a++) {for (int b=0; b <=9;  B + +) {if (a+b = =) {System.out.println ("a=" +a+ "" + "b=" +b+ ""); }}}}</span> 

<span style= "font-size:18px;" >//</span><span style= "FONT-SIZE:18PX; Font-family:arial, Helvetica, Sans-serif; > 99 </span><span style= "FONT-SIZE:18PX;" >private static void Printstring () {System.out.println ("99" Table: "); for (int i = 1; I <= 9;  i + +) {for (int j = 1; J <= I; j + +) {System.out.print (j+ "*" +i+ "=" +i*j+ "); }system.out.println ();} System.out.println ("The 99" table is over!) ");} </span><span style= "FONT-SIZE:18PX; Font-family:arial, Helvetica, Sans-serif; > Array sort </span><span style= "font-size:18px;" >private static int compute (int[] in) {System.out.println ("array sort:"); int temp = 0;for (int i = 0; i < in.length; i + +) { for (int j = 0; J < In.length; J + +) {if (In[i] > In[j]) {temp = In[i];in[i] = in[j];in[j] = temp;}}} for (int k = 0; k < in.length; k + +) {System.out.print (In[k] + ",");} System.out.println ("Sort end! "); return Math.Abs (In[0]-in[in.length-1]);} </span> 

<span style= "FONT-SIZE:18PX;" >//</span><span style= "FONT-SIZE:18PX; Font-family:arial, Helvetica, Sans-serif; > Reverse Output string </span><span style= "FONT-SIZE:18PX;" >private static void GetString (String str) {System.out.println ("Reverse Output string! "); if (str! = null &&!str.isempty ()) {for (int i = Str.length ()-1; I >= 0; i--) {System.out.print (Str.charat (i))}}} </span>

The result is:

<span style= "FONT-SIZE:18PX;" > Enter the number of starts you need to calculate your score, enter the end: 44 * 3 * 2 * 1 = 24 Add nine from zero to 13: a=4 b=9 a=5 b=8 a=6 b=7 a=7 b=6 a=8 b=5 a=9 b=4 99 table: 1*1=1 1*  2=2  2*2=4  1*3=3  2*3=6  3*3=9  1*4=4  2*4=8  3*4=12  4*4=16  1*5=5  2*5=10  3*5=15  4*5=20  5*5=25  1*6=6  2*6=12  3*6=18  4*6=24  5*6=30  6*6=36  1*7=7  2*7=14  3*7=21  4*7=28  5*7=35  6*7=42  7*7=49  1*8=8  2*8=16  3*8=24  4*8=32  5*8=40  6*8=48  7*8=56  8*8=64  1*9=9  2*9=18  3*9=27  4*9=36  5*9=45  6*9=54  7*9=63  8*9=72  9*9=81  99 the table is over!
