Syntax error on token close identifier expected after this token

I was working on a simple program and the same problem would keep coming up. It underlines the word close in input.close(); and I’d search through my program to try and find any errors but to no avail. Here’s my code:

import java.util.Scanner;

Thanks for the help in advance!

In this post, I will be sharing how to fix the syntax error on token «,», { expected after this token error in Java. It is a compile-time error. As the name suggests, this error is syntax-based and mostly faced by Java beginners.

As always, first, we will produce the syntax error on token «,», { expected after this token error before moving on to the solution. Let’s dive deep into the topic:

Note: This compiler error can be produced only in the Eclipse IDE.

[Fixed] Syntax error on token «,», { expected after this token

1. Producing the error

We can easily produce this error in the Eclipse IDE by writing code or executable statements outside the method as shown below:

import java.util.*;

public class SyntaxError {
	String str = "Alive is Awesome";
	Random rand = new Random();
	for (int i = 0; i < 3; i++) {
	    System.out.println(str);		
	}
}

Output:

2. Explanation:

The cause of this error is due to the code or executable statements not present inside the method. You can not directly write the code in a class in Java. Only variables declaration/initialization are allowed outside the method.

3. Solution:

The above compilation error can be resolved by moving the code inside a method. In simple words, you can’t call a class you have to call a method that is declared inside a class. We can easily avoid this error by using one of the solutions given below:

Solution 1: Using public static void main() method

We have moved the code inside the public static void main() method as shown below in the code:

import java.util.*;

public class SyntaxError {
    public static void main(String args[]) {
	String str = "Alive is Awesome";
	Random rand = new Random();
	for (int i = 0; i < 3; i++){
	    System.out.println(str);		
	}
    } 
}    

Solution 2: Using any method

We can move the executable code inside any method, for example, the printString() method as shown below in the code:

import java.util.*;

public class SyntaxError {
    public static void printString() {
	    String str = "Alive is Awesome";
	    Random rand = new Random();
	    for (int i = 0; i < 3; i++){
	        System.out.println(str);		
	    }
    }
    public static void main(String args[]) {
        printString();
    }
}

Solution 3: Using block

Any executable code inside {} without any method name is called a block. We can move the executable code inside the block also as shown below:

import java.util.*;

public class SyntaxError {
    // Using block
    {
	    String str = "Alive is Awesome";
	    Random rand = new Random();
	    for (int i = 0; i < 3; i++){
	        System.out.println(str);		
	    }
    }
    public static void main(String args[]) {
        new SyntaxError();
    }
}

That’s all for today. Please mention in the comments in case you have any questions related to the syntax error on token «,», { expected after this token error in Java.
