没有值的json字符串

Given a string and some of the primitive data type values, we have to concatenate them with the string in Java.

给定一个字符串和一些原始数据类型值，我们必须将它们与Java中的字符串连接起来。

In the example below, we have declared and initialized some of the primitive type of objects and a string object; we are adding the value of primitive types in the string object and printing the values of the result.

在下面的示例中，我们声明并初始化了一些原始类型的对象和一个字符串对象； 我们将在字符串对象中添加基本​​类型的值并打印结果的值 。

带有原始数据类型值的字符串连接的Java代码 (Java code for string concatenation with primitive data type values)

// Java code for string concatenation with 
// primitive data type values
public class Main {
public static void main(String[] args) {
boolean isMarried = false;
boolean isQualified = true;
int age = 21;
double weight = 67.85;
char gender = 'M';
String name = "Shivang Yadav";
String result = null;
result = "isMarried: " + isMarried;
System.out.println(result);
result = "isQualified: " + isQualified;
System.out.println(result);
result = name + " is " + age + " years old.";
System.out.println(result);
result = name + " weight is " + weight + " kg.";
System.out.println(result);
result = "His gender is: " + gender;
System.out.println(result);
}
}

Output

输出量

isMarried: false
isQualified: true
Shivang Yadav is 21 years old.
Shivang Yadav weight is 67.85 kg.
His gender is: M
