How to solve java.lang.NoSuchMethodError: psyche Exception inwards thread "main"
java.lang.NoSucMethodError comes when Java code tries to call a method which is non existed on a class, this could move either static or non static method. most mutual manifestation of java.lang.NoSuchMethodError is running a course of written report which doesn't convey main method inwards Java. In this article nosotros volition come across what is "java.lang.NoSuchMethodError: psyche Exception inwards thread "main"" , Why does java.lang.NoSuchMethodError comes in addition to how to solve java.lang.NoSuchMethodError inwards Java.
What is "java.lang.NoSuchMethodError: psyche Exception inwards thread "main""
This is a manifestation of NoSuchMethodError inwards Java in addition to complaining nearly "main" which is lift of method JVM tries to telephone telephone but doesn't abide by inwards offending class. "java.lang.NoSuchMethodError: psyche Exception inwards thread "main" tin come upward due to diverse reasons like: 1) Class which you lot are trying to run doesn't convey psyche method.
2) Signature of psyche method is non right . See hither for all possible signature of psyche method inwards Java.
Example of "java.lang.NoSuchMethodError: psyche Exception inwards thread "main"
To meliorate empathize NoSuchMethodError in Java let's come across simply about mutual examples of java.lang.NoSuchMethodError and abide by out how in addition to when they come:
1) endeavor to run a coffee course of written report which doesn't convey a psyche method:
public class Loan{
public String getPersonalLoan(){
return "Personal Loan";
};
}
public String getPersonalLoan(){
return "Personal Loan";
};
}
2) Now compile this course of written report it should compile without whatever error:
user@home: /java javac Loan.java
3) Run as "java Loan"
user@home: /java coffee Loan
java.lang.NoSuchMethodError: main
Exception inwards thread "main"
java.lang.NoSuchMethodError: main
Exception inwards thread "main"
There are rattling few scenarios on which java.lang.NoSuchMethodError come upward during runtime because compiler is able to banking concern agree this fault in addition to flag it if doesn't works life the proper method except psyche which is optional method in addition to exclusively checked past times JVM during runtime. As I said before Another possible crusade of "java.lang.NoSuchMethodError: psyche Exception inwards thread "main" is that you lot convey psyche method inwards course of written report but signature of psyche method is non correct. to attempt out this scenario let's
add a psyche method inwards Loan.java
public course of written report Loan{
world String getPersonalLoan(){
provide "Personal Loan";
};
world static void main(String args){
System.out.println("Inside psyche inwards Java");
}
}
world String getPersonalLoan(){
provide "Personal Loan";
};
world static void main(String args){
System.out.println("Inside psyche inwards Java");
}
}
Now compile in addition to run this Java program. You volition all the same get:
java.lang.NoSuchMethodError: psyche Exception inwards thread "main"
because inwards main method args should move string array in addition to nosotros convey non added [] at that spot in addition to that's why this error.
That’s all on How to fix java.lang.NoSuchMethodError: psyche Exception inwards thread "main . Ideally java.lang.NoSuchMethodError comes when nosotros telephone telephone a method which doesn’t exits inwards course of written report but to a greater extent than oftentimes than non typo, wrong declaration or wrong signature turns out to move existent culprit.
