Java 从int输入获取字符串
我需要得到字符串形式的值。我该怎么做?在第一组方向上,我得到了七个整数。所以我把所有的变量都设置为整数,除了player之外,但是我还想把所有的值都设置为字符串Java 从int输入获取字符串,java,java.util.scanner,Java,Java.util.scanner,我需要得到字符串形式的值。我该怎么做?在第一组方向上,我得到了七个整数。所以我把所有的变量都设置为整数,除了player之外,但是我还想把所有的值都设置为字符串 import java.util.Scanner; public class Baseball { public static void main(String[] args) { //opens a new scanner instance Scanner baseball = new Scanner(Sy

Integer.toString(int)代码>有一个类表示每个基元类型。它们包含工具。如果必须将它们作为字符串抓取并转换为int:
将扫描仪从nextInt()
切换到next()
,并使用Integer.parseInt(字符串)代码>您只需执行以下操作:String str=theint+“”
或者棒球。next()要从扫描仪获取字符串,只需使用
int yourValue;
String yourStringFromTheValue = yourValue+"";
您可以使用:
int val = 3 ;
String myStrVal = Integer.toString(val);
double dVal = 3.4;
String myStrVal = Double.toString(dVal);
类似地,对于双值,您可以使用:
int val = 3 ;
String myStrVal = Integer.toString(val);
double dVal = 3.4;
String myStrVal = Double.toString(dVal);
不看代码,只看问题的上半部分,您可能在寻找类似String.valueOf(someInt)
的内容。通过这种方式,您可以将输入接受为整数,但随后将其转换为字符串。只需使用barball.next()
azurefrog-它会出错,因为我的所有变量都是整数,我必须将它们更改为字符串
