jAvA新手编程题目

思路如下: 随即4个数字(1~6) 用来模拟4个色子 数字全部存入数组ary,.然后升序排列. 如果满足两两相等,那么已经排序好的数字,就是ary[0]=ary[1]; ary[2]=ary[3]; 然后判断ary[0]+ary[2]==6 .如果等于6 那么满足要求,不等于6 ,那么继续下次循环 参...

public boolean equals(Student otherStudent){ boolean equal = true; if (this.firstName.length() != otherStudent.firstName.length() ) return false; if (this.lastName.length() != otherStudent.lastName.length() ) return false; for ...

public static void main(String[] args) {String str="9908我";if(str.length()!=5){System.out.println("号码长度有误");}else{//默认标识:标识正确的boolean flag=true;for (int i = 0; i < str.length(); i++) {//拿到每一个字符char every...

两个代码 一个学生类, 一个测试类 你自己把他们放不同包里面 public class Student {private int Snum;private int Gnum;private String Sname;private String Ssex;private int Sage;private static int count = 0;public Student(int snum, i...

public static void main(String[] args) {Scanner scanner = new Scanner(System.in);System.out.print("Please enter first complex number, real numerator> ");int first_real_numerator = scanner.nextInt();System.out.print("Please ente...

用正则表达式就可以了,看示例 public class A { public static void main(String[] args) { String reg = "(\\d+\\.{0,1}\\d+;\\s?){3}(\\d+\\.{0,1}\\d+\\s?)"; String num = "124; 25;12.3;2a"; boolean isRightFormat = num.matches(reg); S...

public static void main(String[] args) { System.out.println(new d().getY(30)); } public double getY(int x){ double y=0.0; y=x*3.14/180; return y; }

//填好了,自己看吧import java.util.*;class Complex{double x,y;Complex(){}Complex(double u,double v) { x=u;y=v; } public void set(double u,double v){ x=u;y=v; } Complex add(Complex w) { Complex c=new Complex(w.x+x,w.y+y); return...

执行结果: 代码如下: public class App73 {public static void main(String[] args) {for (int i = 1; i

先了解思路就很容易了,把十位和百位分别转成个位然后在对十取余就能拿到该数了! 我的思路都在注释里面很详细!不足之处,请多多指教! public class 立方和 {public static void main(String[] args) {System.out.println("\n\t\t==========百位数...
