Java 将键盘中的输入保存到数组

import java.util.Scanner;
import java.util.InputMismatchException; public class saveInputToArr { public static void main(String[] args) { Scanner scan = null;
try {
scan = new Scanner(System.in);
System.out.print( "请输入个数: " );
int inputNum = scan.nextInt();
if( inputNum <= 0 ) {
throw new Exception( "输入有误" );
} System.out.println( "请输入数字: " );
int arr[] = new int[inputNum];
int num = 0;
int count = 0;
while( count < inputNum ) {
num = scan.nextInt();
arr[count] = num;
count++;
} for( int i = 0; i < arr.length; i++ ) {
System.out.print( arr[i] + " " );
}
} catch ( Exception e ) {
throw new InputMismatchException( "\u8f93\u5165\u6709\u8bef\u002c\u0020\u8bf7\u91cd\u65b0\u8f93\u5165" );
} finally {
try {
if ( scan != null ) {
scan.close();
}
} catch ( Exception e2 ) {
e2.printStackTrace();
}
} } }

运行结果为:
