Sprintf等同于Java [英] Sprintf equivalent in Java

问题描述

Printf被1.5版本添加到了Java中，但我似乎无法找到如何将输出发送到字符串而不是文件（这是sprintf在C中的做法）。有谁知道如何做到这一点？

解决方案

  //将格式化的字符串存储在'result'中
字符串结果= String.format（％4d，i * j）; 
 
 //将结果写入标准输出
 System.out.println（result）; 
  

请参阅 format 及其语法

Printf got added to Java with the 1.5 release but I can't seem to find how to send the output to a string rather than a file (which is what sprintf does in C). Does anyone know how to do this?

解决方案

// Store the formatted string in 'result'
String result = String.format("%4d", i * j);

// Write the result to standard output
System.out.println( result );
