Convert Char to String Using `valueOf()` Method

Open your terminal and create a Java file using the below command:
```
touch ConvertCharToString.java
```

Open the file using a text editor and paste the below code:

public class ConvertCharToString {
  public static void main(String[] args) {
    char ch = 's';
    System.out.println(ch);
    String str = String.valueOf(ch);
    System.out.println(str);
    System.out.println(str.getClass().getName());
  }
}

Compile the Java code using the below command in the terminal:
```
javac ConvertCharToString.java
```
Run the Java code using the below command in the terminal:
```
java ConvertCharToString
```
The output will be:
```
s
s
java.lang.String
```

Convert Char to String Using `toString()` Method

Open the same ConvertCharToString.java file in the text editor and replace the main method with the below code:

public static void main(String[] args){
  char ch = 's';
  System.out.println(ch);
  String str = Character.toString(ch);
  System.out.println(str);
  System.out.println(str.getClass().getName());
}

Compile the Java code using the below command in the terminal:
```
javac ConvertCharToString.java
```
Run the Java code using the below command in the terminal:
```
java ConvertCharToString
```
The output will be:
```
s
s
java.lang.String
```

Convert Char to String Using `+` Operator

Open the same ConvertCharToString.java file in the text editor and replace the main method with the below code:

public static void main(String[] args){
  char ch = 's';
  System.out.println(ch);
  String str = ""+ch;
  System.out.println(str);
  System.out.println(str.getClass().getName());
}

Compile the Java code using the below command in the terminal:
```
javac ConvertCharToString.java
```
Run the Java code using the below command in the terminal:
```
java ConvertCharToString
```
The output will be:
```
s
s
java.lang.String
```
