Java 中的 PrintStream 打印(浮点)方法,示例
原文:https://www . geesforgeks . org/print stream-print float-method-in-Java-with-examples/
Java 中的print(float)print stream类的方法用于在流上打印指定的 float 值。这个浮点值被当作一个参数。
语法:
public void print(float floatValue)
参数:该方法接受一个强制参数浮点值,即要写入流的浮点值。
返回值:此方法不返回值。
下面的方法说明了打印(浮动)的工作方法:
程序 1:
// Java program to demonstrate
// PrintStream print(float) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(System.out);
// Print the float value '4.5'
// to this stream using print() method
// This will put the floatValue in the
// stream till it is printed on the console
stream.print(4.5);
stream.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
4.5
程序 2:
// Java program to demonstrate
// PrintStream print(float) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(System.out);
// Print the float value '1.65'
// to this stream using print() method
// This will put the floatValue in the
// stream till it is printed on the console
stream.print(1.65);
stream.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
Output:
1.65
