大神們好,原本我想寫(xiě)一個(gè)代碼如下,但卻報(bào)錯(cuò)如下,只想問(wèn)是哪裡出錯(cuò)了: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - non-static method isKeyRow(java.lang.String) cannot be referenced from a static contextat javaapplication3.JavaApplication3.main(JavaApplication3.java:12)C:UsersViviAppDataLocalNetBeansCache8.2executor-snippetsrun.xml:53: Java returned: 1 BUILD FAILED (total time: 1 second) 本人是java新手,可以幫忙解惑嗎? package javaapplication3; import java.util.Scanner; public class JavaApplication3 { public static void main(String[] args) { System.out.println(isKeyRow("user")); } public boolean isKeyRow(String user){ String string1="qwertyuiop"; String string2="asdfghjkl"; String string3="zxcvbnm"; Character u; boolean b=true; for(int i=0;i<user.length();i++){ u=user.charAt(i); for(int a=0;a<string1.length();a++){ if(string1.charAt(a)!=u){ b=false; break; } } for(int a=0;a<string2.length();a++){ if(string2.charAt(a)!=u){ b=false; break; } } for(int a=0;a<string3.length();a++){ if(string3.charAt(a)!=u){ b=false; break; } return b; } }
