有哪位高手可以帮忙做下题目呀？？ ⒈求出以下语句的运行结果。 int e = Integer.parseInt(3+"" + 5); System.out.println(e - 1.5); ⒉已知文件file1.txt的内容是“mnopqrasdfgh”,求出运行结果。import java.io.*;public class jts02{ public static void main(String args[]){ try{ FileInputStream rf=new FileInputStream("file1.txt"); int len,i,j;len=rf.available(); System.out.println("len="+len); FileOutputStream wf=new FileOutputStream("file2.txt"); byte b[]=new byte[len]; byte c; rf.read(b,0,len); for(i=0,j=len-1; i 0){ sum+=n;n- -;} return sum;} public static void main(String[] args) { int x=5; jts03 f=new jts03(); System.out.println("sumd="+ f.sumd(x)); String a="4"; int b= Integer.parseInt(a);System.out.println("sumd="+ f.sumd(b)); }}⒋求出运行结果public class jts04 { int i[] = {4,0,3}; public static void main(String args[]) { int i[] = {8,1,7}; conve(i); System.out.println("3==="+i[2]); } public static void conve(int i[]) { int j[] = {5,2,6}; System.out.println("1==="+i[1]); i = j; System.out.println("2==="+i[1]); }} ⒌求出运行结果import java.io.*;public class jts05{ public static void main(String[] args) { Person [] staff = new Person [3]; staff[2] = new Person (9907101L,"毛以超",19840103L,'男'); staff[1] = new Person (9910422L,"马志明",19821202L,'女'); staff[0] = new Person (9907112L,"陈丽红",19800203L,'男'); for (int i = staff.length-1; i >= 0 ; i--) staff[i].print();}}class Person { public Person (long gh, String name,long date,char sex) { this.gh=gh;this.name=name;this.date= date;this.sex=sex; System.out.println("工号为"+gh+"的工友构造成功"); }; public void print(){ System.out.println( "工号 " + gh+" 姓名 "+name); } private long gh; private String name; private long date; private char sex; };⒍求出运行结果import java.util.*;public class jts06{ public static void main(String[] args) { Student liu=new Student(9910422,"方晓峰",19801203,'M'); Student zhang=new Student(); zhang=liu; zhang.print();liu.print(); liu=new Student(9911242,"周家棋",19801203,'M');zhang.print();liu.print(); zhang=new Student(liu); liu=new Student(9910422,"方晓峰",19801203,'M');zhang.print();liu.print();} }class Student { public Student(long a, String b,long c,char d) { xh = a; name=b; date=c; sex =d; }; public Student(Student a) { xh = a.xh; name=a.name; date=a.date; sex =a.sex; }; public Student(){}; public void print() { System.out.println( "学号 " + xh+" 姓名 "+name ); }
