PrintWriter 用 Java 打印(字符串)方法，示例
原文:https://www . geesforgeks . org/print writer-print string-method-in-Java-with-examples/
Java 中 PrintWriter 类的 print(String) 方法用于在流上打印指定的 String 值。该字符串值被视为参数。
语法:
public void print(String StringValue)
参数:该方法接受一个强制参数字符串值，它是要写入流的字符串值。
返回值:此方法不返回值。
以下方法说明了打印(字符串)方法的工作原理:
程序 1:
// Java program to demonstrate
// PrintWriter print(String) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintWriter instance
PrintWriter writer
= new PrintWriter(System.out);
// Print the String value 'GeeksForGeeks'
// to this stream using print() method
// This will put the StringValue in the
// stream till it is printed on the console
writer.print("GeeksForGeeks");
writer.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
GeeksForGeeks
程序 2:
// Java program to demonstrate
// PrintWriter print(String) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintWriter instance
PrintWriter writer
= new PrintWriter(System.out);
// Print the String value 'GFG'
// to this stream using print() method
// This will put the StringValue in the
// stream till it is printed on the console
writer.print("GFG");
writer.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
GFG
