比较运算的结果是一个布尔值,如果为true,则表示比较条件成立;如果为false,则表示比较条件不成立。 if(result){System.out.println("num1 < num2");}else{System.out.println("num1 >= num2");} 1. 2. 3. 4. 5. 在上述代码中,我们使用if-else语句根据比较的结果输出不同的信息。如果result为true,则...
下面是一个示例代码,演示了short类型的判断: shortnum=-500;if(num<0){System.out.println("Negative");}elseif(num==0){System.out.println("Zero");}else{System.out.println("Positive");} 1. 2. 3. 4. 5. 6. 7. 8. 在上述代码中,我们定义了一个short类型的变量num,并将其值设置为-500。...
Short Hand if...elseThere is also a short-hand if else, which is known as the ternary operator because it consists of three operands.It can be used to replace multiple lines of code with a single line, and is most often used to replace simple if else statements:...

short a = 32767; short b = 1; if (a > Short.MAX_VALUE - b) { System.out.println("Overflow will occur!"); } else { short result = (short) (a + b); System.out.println("Result: " + result); } 复制代码 使用Java 8 中的 Math.addExact() 和Math.subtractExact() 方法:这些方法...
在Java中,`short`是一个基本数据类型,用于存储16位有符号整数。它的取值范围是-32,768到32,767。使用`short`类型可以节省内存空间,特别是在处理大量数据时。以下是一些建议,可...
代码语言:java 复制 byte b = 127; // 假设字节为127 short s; if (b < 0) { s = (short) ((b & 0xFF) | 0x8000); // 进行符号扩展 } else { s = (short) (b & 0xFF); // 不进行符号扩展 } System.out.println("转换后的short值为:" + s); 字节转换为整数的过程类似,只是目标...
如果您需要确保int值在Java 8和Java 7上保持一致,可以使用以下方法: 代码语言:txt 复制 int num = 123; if (num > 0xFFFF) { 代码语言:txt 复制 short unsignedShort = (short) (num | 0x1000); } else { 代码语言:txt 复制 } 代码语言:txt ...
