编写java应用程序

[sayidming]

public class UseArray{
public static void main(String x[]){
System.out.println("输入的数组元素:"+x.length);
for(int i=0;i<x.length;i++)
System.out.print(" x["+i+"]="+x[i]);

System.out.println();

int min=x[0],max=x[0],sum=0;
for(int i=0;i<x.length;i++){
sum+=x[i];
if(x[i]>max)
max=x[i];
if(x[i]<min)
min=x[i];
}
System.out.println("数组元素的和:\t"+sum);
System.out.println("元素的最大值:\t"+min);
System.out.println("数组元素的最小值:\t"+max);
}

}


//输入数组，求数组元素的和、数组元素的最大值和最小值并输出所求结果。
我不知道错在哪里？哪位大虾帮我修改下，谢谢！

//初始化int x[]={5,24,3,5,321,54,545,12,};
public class UseArray{
public static void main(String args[]){
int x[]={5,24,3,5,321,54,545,12,};
System.out.println("输入的数组元素:"+x.length);
for(int i=0;i<x.length;i++)
System.out.print(" x["+i+"]="+x[i]);
System.out.println();

int min=x[0];
int max=x[0];
int sum=0;
for(int i=0;i<x.length;i++){
sum+=x[i];
if(x[i]>max)
max=x[i];
if(x[i]<min)
min=x[i];
}
System.out.println("数组元素的和:\t"+sum);
System.out.println("元素的最大值:\t"+min);
System.out.println("数组元素的最小值:\t"+max);

要求可以任意输入数组，不是指定的

[Parson]

public class ArrayTest {
public static void main(String x[]) {
System.out.println("输入的数组元素:" + x.length);
if (x.length == 0) {
return;
}
for (int i = 0; i < x.length; i++) {
System.out.print(" x[" + i + "]=" + x[i]);
}
System.out.println();

int min = Integer.MAX_VALUE, max = Integer.MIN_VALUE, sum = 0;
for (int i = 0; i < x.length; i++) {
int value = Integer.parseInt(x[i]);
sum += value;
if (value > max) {
max = value;
}
if (value < min) {
min = value;
}
}
System.out.println("数组元素的和:\t" + sum);
System.out.println("元素的最大值:\t" + max);
System.out.println("数组元素的最小值:\t" + min);
}
}

//加入错误处理

public class ArrayTest {
public static void main(String x[]) {
System.out.println("输入的数组元素:" + x.length);
if (x.length == 0) {
return;
}
for (int i = 0; i < x.length; i++) {
System.out.print(" x[" + i + "]=" + x[i]);
}
System.out.println();

int min = Integer.MAX_VALUE, max = Integer.MIN_VALUE, sum = 0;
for (int i = 0; i < x.length; i++) {
try {
int value = Integer.parseInt(x[i]);

sum += value;
if (value > max) {
max = value;
}
if (value < min) {
min = value;
}
}
catch (NumberFormatException e) {
System.out.println("输入了非法数字：\t" + x[i]);
return;
}
}
System.out.println("数组元素的和:\t" + sum);
System.out.println("数组元素的最大值:\t" + max);
System.out.println("数组元素的最小值:\t" + min);
}
}
