Array 的用法举例.doc

范例：public class arrayc public static void main(String args) int i; int a=15,6,8,9; for(i=0;i System.out.print(a+i+=+ai+,t); System.out.println(a.length); 范例：public class arrayc public static void main(String args) int i; int a=new int3; for(i=0;imax) max=ai; if(ai min=ai; System.out.println(n the max value is+max); System.out.println(the min value is+min); 范例：二维数组：public class arrayc public static void main(String args) int values =1,2,3,4; int sum=0; System.out.println(the array length=+values.length); System.out.println(elements in the array are); for(int i=0;i for(int j=0;j sum+=valuesij; System.out.println(valuesij); System.out.println(the sum=+sum); 范例：求最大与最小值的另一中方法：public class arrayc public static void main(String args) int a=14,25,36,47,58,69; max(a); static void max(int b) int ma,mi; ma=mi=b0; for(int i=0;i if(bima) ma=bi; else if(bi mi=bi; System.out.println(the length of the array is+b.length); System.out.println(the max number is=+ma); System.out.println(the min number is=+mi); 范例：二维数组：public class arrayc public static void main(String args) int a=12,25,24,16,13,15,28,16,17,17,15; printarray(a); static void printarray(int b) for(int i=0;i for(int j=0;j System.out.print(bij+ ); System.out.println(); 范例：数组的排序方法：public class arraysort public static void main(String args) int myarray= 55,2,6,4,32,12,-9,73,26,37; System.out.println(原始数据为); for(int i=0;i System.out.print(myarrayi+ ,); arraysort myarraysort=new arraysort(); int result=myarraysort.sort(myarray); System.out.println(n排序后的数据); for(int i=0;i System.out.print(resulti+ ,); public int sort(int a) int temp,size=a.length; for(int i=size-1;i=1;i-) boolean end=true; for(int j=0;j if(ajaj+1) temp=aj; aj=aj+1; aj+1=temp; end=false; if(end=true) break; return a;范例：数组排序的第二中方法class arraysort public static void main(String args) int n; int a=new int1; int b=20,36,25,69,47,45,46,98; System.out.println(排序前：); for(n=0;n System.out.print( +bn); for(int i=0;i for(int j=i+1;j if(bibj) a0=bi; bi=bj; bj=a0; System.out.println(n排序后：); for(int m=0;m System.out.print( +bm); 范例：数组的查询方法：import java.io.*;class arraysearch public static void main(String args) throws IOException BufferedReader mybuf=new BufferedReader(new InputStreamReader(System.in); int search=0; String mystring; int a=25,23,21,32,36,35,34,58,69,54,47; System.out.println(数组 a 所包含的元素为：); for(int i=0;i System.out.print( +ai); System.out.println(n请输入你所要查询的元素); try mystring=mybuf.readLine(); search=Integer.parseInt(mystring);catch(Exception e); boolean found=false; int j; for(j=0;j if
