Java's two-cycle code sample

1. Calculate the average of three classes

Import Java.util.Scanner;

public class avgscore{

public static void Main (sting[] args) {

Int[] score = new int[]; Result array

int classnum = 3; Number of Classes

Double sun = 0.0; Total Score

double[] Average = new double[classnum];//average score array

Cycle Input Student Scores

Scanner input = new Scanner (system.in);

for (int i =0; i<classnum; i++) {//Outer loop control class

sum = 0.0//sum of scores zeroed

System.out.println ("Please enter" + (i+1) + "Student's score:");

for (int j=0; j<score.length; J + +) {//Inner loop control number of participants per class

System.out.print ("the" + (j+1) + "Student's score:");

SCORE[J] = Input.nextint ();

sum = sum+score[j];//score Accumulation

}

Average[i] = sum/score.length;//average divide calculation

System.out.println ("the" + (i+1) + "class participants ' average score is:" +average[i]+ "\ n");

}

}

}

2. Print a rectangular code example

public class rtriangle{

Public satic void Main (string[] args) {

System.out.println ("Print rectangle");

for (int i = 1; i<= 5; i++) {//Print line I

for (Int J =1; j<=5;j++) {//print five * numbers

System.out.print ("*");

}

System.out.println ("\ n"); Line break

}

}

}

3. Bubble sort

Package Cn.jbit.ifdemo;

Import Java.util.Scanner;

/*

* Bubble sort 5 students score

**/

public class sortscore{

public static void Main (string[] args) {

Int[] Scores=new int[5];

Scanner input=new Scanner (system.in)

System.out.println ("Please enter the results of 5 students:");

Get student Results

for (int i = 0; i<scores.length;i++) {

System.out.pint ("Please enter" + (i+1) + "Student Score:");

Scores[i]=input.nextint ();

}

Bubble Sort Student Score

for (int i=0; i<scores.length-1; i++) {

for (int j=0; j<score.length-1-i; J + +) {

if (Scores[j]<scores[j+1]) {

int TEMP=SCORES[J];

SCORES[J]=SCORES[J+1];

Scores[j+i] =temp;

}

}

}

System.out.println ("Post-sorting results:");

for (int score:scores) {

System.out.print (score+ "\ t");

}

}

}
