Java基礎-while循環(huán)語句、循環(huán)嵌套_百度文庫

1、1. 使用while循環(huán)，求1+11+111+1111+11111+111111。public class Test public static void main(String args int i = 0;double n = 0;double sum = 0;while(i<6n = n+Math.pow(10,i;sum =sum+n;i+;System.out.println("1+11+111+1111+11111+111111="+sum; 2. 求10的階乘 1x2x3x4x10.public class Test public static void

2、 main(String args int result = 1;for(int i = 10;i > 0;i-result *= i;System.out.println("10!="+result; 3. 求1+2+3+1000的和，把和輸出，計算每步結果中有多少個最后以8結尾的。public class Test public static void main(String args int sum = 0;int n = 0;for (int i = 1; i <= 1000; i+ sum += i;if(sum%10 = 8n+; System.ou

3、t.println("1+2+3+1000="+sum;System.out.println("每步結果中以8結尾有"+n+"個." 4. 計算1+2+3，直到和大于500，程序退出，輸出結果。public class Test public static void main(String args int sum = 0;boolean bol = true;for (int i = 1; i <= 1000; i+ while (bol sum += i;if (sum > 500 bol = false;System

4、.out.println("1+2+3和大于500,結果=" + sum;5. 輸出下列圖案11 21 2 31 2 3 41 2 3 4 51 2 3 4 5 6 1 10public class Test public static void main(String args for(int i = 1;i <= 10;i+for(int j = 1;j <= i;j+System.out.print(" "+j;System.out.println(;6. 某人工資為6000/月，工資月增長率為0.5%，工作20年，共得到多少工資。pu

5、blic class Test public static void main(String args double allMoney = 6000;double monthWages = 6000;for(int i = 2;i <= 20*12;i+monthWages = monthWages+monthWages*Math.pow(0.005, i-1;allMoney += monthWages; System.out.println("工作20年工資="+allMoney;7. 100到200之間，所有能被5或6整除，但不能同時整除的數，每行顯示10個。p

6、ublic class Test public static void main(String args int j = 1;for (int i = 100; i <= 200; i+ if (i % 5 = 0 | i % 6 = 0 if (i % 30 != 0 if (j < 10 System.out.print(i+" "j+; else System.out.println(i;j = 1;8. 打印乘法口訣表。public class Test public static void main(String args for (int i = 1; i <= 9; i+ for(int j = 1;j
