    題目:古典問題:有一對兔子,從出生后第3個月起每個月都生一對兔子,小兔子長到第三個月后每個月又生一對兔子,假如兔子都不死,問每個月的兔子總數(shù)為多少?    //這是一個菲波拉契數(shù)列問題 public class lianxi01 { public static void main(String[] args) { System.out.println("第1個月的兔子對數(shù):    1"); System.out.println("第2個月的兔子對數(shù):    1"); int f1 = 1, f2 = 1, f, M=24;      for(int i=3; i<=M; i++) {       f = f2;       f2 = f1 + f2;       f1 = f;       System.out.println("第" + i +"個月的兔子對數(shù): "+f2);          } } } 【程序2】    題目:判斷101-200之間有多少個素數(shù),并輸出所有素數(shù)。 程序分析:判斷素數(shù)的方法:用一個數(shù)分別去除2到sqrt(這個數(shù)),如果能被整除, 則表明此數(shù)不是素數(shù),反之是素數(shù)。    public class lianxi02 { public static void main(String[] args) {     int count = 0;     for(int i=101; i<200; i+=2) {      boolean b = false;      for(int j=2; j<=Math.sqrt(i); j++)      {         if(i % j == 0) { b = false; break; }          else           { b = True; }      }         if(b == True) {count ++;System.out.println(i );}                                   }     System.out.println( "素數(shù)個數(shù)是: " + count); } } 【程序3】    題目:打印出所有的 "水仙花數(shù) ",所謂 "水仙花數(shù) "是指一個三位數(shù),其各位數(shù)字立方和等于該數(shù)本身。例如:153是一個 "水仙花數(shù) ",因為153=1的三次方+5的三次方+3的三次方。 public class lianxi03 { public static void main(String[] args) {      int b1, b2, b3;

  • JAVA SMPP 源碼

    Introduction jSMPP is a java implementation (SMPP API) of the SMPP protocol (currently supports SMPP v3.4). It provides interfaces to communicate with a Message Center or an ESME (External Short Message Entity) and is able to handle traffic of 3000-5000 messages per second. jSMPP is not a high-level library. People looking for a quick way to get started with SMPP may be better of using an abstraction layer such as the Apache Camel SMPP component: http://camel.apache.org/smpp.html Travis-CI status: History The project started on Google Code: http://code.google.com/p/jsmpp/ It was maintained by uudashr on Github until 2013.

  • java實現(xiàn)大整數(shù)運算

    在包 hugeinteger 中創(chuàng)建功能類 HugeInteger,該類用來存放和操作一個不超過 40 位的大整數(shù)。 (1) 定義一個構(gòu)造函數(shù),用來對大整數(shù)進行初始化。參數(shù)為一個字符串。 (2) 定義 input 成員函數(shù),實現(xiàn)大整數(shù)的重新賦值。參數(shù)為一個字符串,無返回 值。 (3) 定義 output 成員函數(shù),將大整數(shù)輸出到屏幕上。無參數(shù)無返回值。 (4) 定義 add 成員函數(shù),實現(xiàn)兩個大整數(shù)的加法。參數(shù)為一個 HugeInteger 對 象,無返回值,例如: HugeInteger A = new HugeInteger("12345"); HugeInteger B = new HugeInteger("1234"); A.add(B); 此時,A 為 13579,B 為 1234。 (5) 定義 sub 成員函數(shù),實現(xiàn)兩個大整數(shù)的減法。參數(shù)和返回值同 add 函數(shù)。 (6) 定義若干大整數(shù)關(guān)系運算的成員函數(shù),包括 isEqualTo(等于,=)、 isNotEqualTo(不等于,≠)、isGreaterThan(大于,>)、isLessThan(小 于,<)、isGreaterThanOrEqualTo(大于等于,≥)和 isLessThanOrEqualTo (小于等于,≤)。這些函數(shù)的參數(shù)為一個 HugeInteger 對象,返回值為一個 布爾類型,表示關(guān)系運算的結(jié)果,例如: HugeInteger A = new HugeInteger("12345"); HugeInteger B = new HugeInteger("1234"); 那么此時 A.isGreaterThan(B)的結(jié)果應(yīng)當為 True,表示 12345>1234。

  • AD826

    High-Speed, Low-Power Dual Operational Amplifier The AD826 features high output current drive capability of 50 mA min per amp, and is able to drive unlimited capacitive loads. With a low power supply current of 15 mA max for both amplifiers, the AD826 is a True general purpose operational amplifier. The AD826 is ideal for power sensitive applications such as video cameras and portable instrumentation. The AD826 can operate from a single +5 V supply, while still achieving 25 MHz of band width. Furthermore the AD826 is fully specified from a single +5 V to ±15 V power supplies. The AD826 excels as an ADC/DAC buffer or active filter in data acquisition systems and achieves a settling time of 70 ns to 0.01%, with a low input offset voltage of 2 mV max. The AD826 is available in small 8-lead plastic mini-DIP and SO packages.
