The clearError() method of PrintStream Class in Java is used to clear the error state of this PrintStream instance. It clears any error that might have or not happened in the stream. Hence the checkError() method will always return false after this method.
Syntax:
protected void clearError()
Parameters: This method do not accepts any parameter.
Return Value: This method do not returns any value.
Below methods illustrates the working of clearError() method:
Program 1:
// Java program to demonstrate// PrintStream clearError() method import java.io.*; class GFG extends PrintStream { // Defining the protected constructor public GFG(OutputStream out) { super(System.out); } // Driver Code public static void main(String[] args) { // The string to be written in the Stream String str = "GeeksForGeeks"; try { // Create a PrintStream instance GFG stream = new GFG(System.out); // Write the above string to this stream // This will put the string in the stream // till it is printed on the console stream.print(str); // Now clear the stream // using clearError() method stream.clearError(); System.out.println("\nHas any error occurred: " + stream.checkError()); } catch (Exception e) { System.out.println(e); } }} |
Output:
GeeksForGeeks Has any error occurred: false
Program 2:
// Java program to demonstrate// PrintStream clearError() method import java.io.*; class GFG extends PrintStream { // Defining the protected constructor public GFG(OutputStream out) { super(System.out); } // Driver Code public static void main(String[] args) { // The string to be written in the Stream String str = "GeeksForGeeks"; try { // Create a PrintStream instance GFG stream = new GFG(System.out); // Write the char to this stream // This will put the char in the stream // till it is printed on the console stream.write(65); // Now clear the stream // using clearError() method stream.clearError(); System.out.println("\nHas any error occurred: " + stream.checkError()); } catch (Exception e) { System.out.println(e); } }} |
Output:
A Has any error occurred: false
