Question

谁知道怎么用java编写程序，用来输出数组最大值，最小值和平均值

Answer 1

public class MaxMin {

public static void main(String[] args) {

Integer[] inte = {12,23,54,75,86};
int max = inte[0];
int min = inte[0];
int average = 0;
int sum = 0;

for(int i=0;i<inte.length;i++){
if(max<inte[i]){
max = inte[i];
}
if(min>inte[i]){
min = inte[i];
}
sum += inte[i];
}
average = sum/inte.length;
System.out.println("最大值----"+max);
System.out.println("最小值----"+min);
System.out.println("平均值----"+average);

}

}

Answer 2

public class re {

/**
* @param args
*/
public static void main(String[] args) {

Integer[] shui = {1,5,8,6,72,};
int da =0;
int xiao =shui[0];
double he = 0;
double ping=0;

for(int i=0;i<shui.length;i++){
if(da <shui[i]){
da =shui[i];
}

if(xiao>shui[i]){
xiao = shui[i];
}
he += shui[i];
}
ping=he/shui.length;

System.out.println("最大值："+da );
System.out.println("最小值："+xiao );
System.out.println("平均值："+ping);

}

}
