Methods for outputting aligned strings in Java include: using format specifiers to specify alignment, padding characters, and field width. Use the String.format() method. Use the StringUtils.center() method of the Apache Commons Lang library.
String alignment in Java
How to output aligned strings?
Java provides a variety of methods to output aligned strings, including:
Using format specifiers
Format specifiers Can be used to specify the alignment of a string. The format specifier consists of the following parts:
- Alignment flags: Indicates the alignment of the string (left, right, or center).
- Padding characters: is used to fill unused spaces.
- Field width: Specifies the minimum width of the string.
For example, the following code right-aligns the string "Hello" and fills the gaps:
System.out.printf("%10s", "Hello");
Use the String.format() method
String.format()
The method can also be used to align strings. It uses a similar syntax to the format specifier:
String formattedString = String.format("%10s", "Hello");
Using the StringUtils library (Apache Commons Lang)
The Apache Commons Lang library provides a StringUtils
Class containing many utility methods for string manipulation, including alignment methods.
For example, the following code center-aligns the string "Hello":
String centeredString = StringUtils.center("Hello", 10);

Java code can run on different operating systems without modification, because Java's "write once, run everywhere" philosophy is implemented by Java virtual machine (JVM). As the intermediary between the compiled Java bytecode and the operating system, the JVM translates the bytecode into specific machine instructions to ensure that the program can run independently on any platform with JVM installed.

The compilation and execution of Java programs achieve platform independence through bytecode and JVM. 1) Write Java source code and compile it into bytecode. 2) Use JVM to execute bytecode on any platform to ensure the code runs across platforms.

Java performance is closely related to hardware architecture, and understanding this relationship can significantly improve programming capabilities. 1) The JVM converts Java bytecode into machine instructions through JIT compilation, which is affected by the CPU architecture. 2) Memory management and garbage collection are affected by RAM and memory bus speed. 3) Cache and branch prediction optimize Java code execution. 4) Multi-threading and parallel processing improve performance on multi-core systems.

Using native libraries will destroy Java's platform independence, because these libraries need to be compiled separately for each operating system. 1) The native library interacts with Java through JNI, providing functions that cannot be directly implemented by Java. 2) Using native libraries increases project complexity and requires managing library files for different platforms. 3) Although native libraries can improve performance, they should be used with caution and conducted cross-platform testing.

JVM handles operating system API differences through JavaNativeInterface (JNI) and Java standard library: 1. JNI allows Java code to call local code and directly interact with the operating system API. 2. The Java standard library provides a unified API, which is internally mapped to different operating system APIs to ensure that the code runs across platforms.
