1、
（1）源程序如下：
public class One {
public static void main(String[] args) {
String name = "張三";
int age = 23;
char sex = '男';
String myclass = "某某專業(yè)2班";
System.out.println("姓名：" + name);
System.out.println("姓名：" + age);
System.out.println("姓名：" + sex);
System.out.println("姓名：" + myclass);
}
}
（2）
編寫完程序的后綴名是.java，如本題，文件名就是One.java。
開始\運行\(zhòng)cmd，進入“命令提示符窗口”，然后用javac編譯器編譯.java文件，語句：javac One.java。
（3）
編譯成功后，生成的文件名后綴是.class，叫做字節(jié)碼文件。再用java解釋器來運行改程序，語句：java One
2、編寫程序，輸出1到100間的所有偶數(shù)
（1）for語句
public class Two1 {
public static void main(String[] args) {
for(int i=2;i=100;i+=2)
System.out.println(i);
}
}
（2）while語句
public class Two2 {
public static void main(String[] args) {
int i = 2;
while (i = 100) {
System.out.println(i);
i += 2;
}
}
}
（3）do…while語句
public class Two3 {
public static void main(String[] args) {
int i = 2;
do {
System.out.println(i);
i += 2;
}while(i=100);
}
}
3、編寫程序，從10個數(shù)當(dāng)中找出最大值。
（1）for循環(huán)
import java.util.*;
public class Three1 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int number;
int max = 0;
for (int i = 0; i 10; i++) {
System.out.print("輸入第" + (i + 1) + "個數(shù):");
number = input.nextInt();
if (max number)
max = number;
}
System.out.println("最大值：" + max);
}
}
（2）while語句
import java.util.*;
public class Three2 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int number;
int max = 0;
int i = 0;
while (i 10) {
System.out.print("輸入第" + (i + 1) + "個數(shù):");
number = input.nextInt();
if (max number)
max = number;
i++;
}
System.out.println("最大值：" + max);
}
}
（3）do…while語句
import java.util.*;
public class Three3 {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int number;
int max = 0;
int i = 0;
do {
System.out.print("輸入第" + (i + 1) + "個數(shù):");
number = input.nextInt();
if (max number)
max = number;
i++;
}while(i10);
System.out.println("最大值：" + max);
}
}
4、編寫程序，計算從1到100之間的奇數(shù)之和。
（1）for循環(huán)
public class Four1 {
public static void main(String[] args) {
int sum=0;
for(int i = 1;i=100;i+=2){
sum+=i;
}
System.out.println("1~100間奇數(shù)和：" + sum);
}
}
（2）while語句
public class Four2 {
public static void main(String[] args) {
int sum = 0;
int i = 1;
while (i = 100) {
sum += i;
i += 2;
}
System.out.println("1~100間奇數(shù)和：" + sum);
}
}
（3）do…while語句
public class Four3 {
public static void main(String[] args) {
int sum = 0;
int i = 1;
do {
sum += i;
i += 2;
} while (i = 100);
System.out.println("1~100間奇數(shù)和：" + sum);
}
}
5、
（1）什么是類的繼承？什么是父類？什么是子類？舉例說明。
繼承:是面向?qū)ο筌浖夹g(shù)當(dāng)中的一個概念。如果一個類A繼承自另一個類B，就把這個A稱為"B的子類"，而把B稱為"A的父類"。繼承可以使得子類具有父類的各種屬性和方法，而不需要再次編寫相同的代碼。在令子類繼承父類的同時，可以重新定義某些屬性，并重寫某些方法，即覆蓋父類的原有屬性和方法，使其獲得與父類不同的功能。另外，為子類追加新的屬性和方法也是常見的做法。繼承需要關(guān)鍵字extends。舉例：
class A{}
class B extends A{}
//成員我就不寫了，本例中，A是父類，B是子類。
（2）編寫一個繼承的程序。
class Person {
public String name;
public int age;
public char sex;
public Person(String n, int a, char s) {
name = n;
age = a;
sex = s;
}
public void output1() {
System.out.println("姓名：" + name + "\n年齡:" + age + "\n性別:" + sex);
}
}
class StudentPerson extends Person {
String school, department, subject, myclass;
public StudentPerson(String sc, String d, String su, String m, String n,
int a, char s) {
super(n, a, s);
school = sc;
department = d;
subject = su;
myclass = m;
}
public void output2() {
super.output1();
System.out.println("學(xué)校：" + school + "\n系別:" + department + "\n專業(yè):"
+ subject + "\n班級:" + myclass);
}
}
public class Five2 {
public static void main(String[] args) {
StudentPerson StudentPersonDemo = new StudentPerson("某某大學(xué)", "某某系別",
" 某專業(yè)", "某某班級", " 張三", 23, '男');
StudentPersonDemo.output2();
}
}

這兩道題代碼怎么寫java？
