Java 输入多行字符串或者多个int数值的方法

import java.util.scanner;

public class main {

  public static void main(string[] args) {

   inputstr();

   input int eger();

   inputintinline();

  }

  //每行输入一个数值，输入多个数值

  public static void inputinteger() {

   scanner scanner = new scanner(system.in);

   string nextline = scanner.nextline();

   int sum = 0 ;

   while (nextline != null && !nextline.equals( "" )) {

    sum += integer.parseint(nextline);

    system.out.println(sum);

    nextline = scanner.nextline();

   }

   system.out.println( "end of input integer" );

  }

  // 每行输入一个 字符串 ，输入多个字符串

  public static void inputstr() {

   scanner scanner = new scanner(system.in);

   string nextline = scanner.nextline();

   while (nextline != null && !nextline.equals( "" )) {

    system.out.println(nextline);

    nextline = scanner.nextline();

   }

   system.out.println( "end of input string" );

  }

  //输入多个数值，用空格隔开

  public static void inputintinline() {

   scanner scanner = new scanner(system.in);

   string str = scanner.nextline();

   string[] numstr = str.split( " " );

   int [] nums = new int [numstr.length];

   for ( int i = 0 ; i < numstr.length; i ++) {

    nums[i] = integer.parseint(numstr[i]);

   }

   for ( int n: nums) {

    system.out.println(n);

   }

   system.out.println( "end of input int in a line" );

  }

}

import java.util.scanner;

public class main{

  public static void main(string[] args){

   scanner in = new scanner(system.in);

//  while(in.hasnextline()){

   while (in.hasnext()){

    string str = in.nextline();

    system.out.println(str);

   }

  }
