How can Java loop statements be written?

In Java, there are several common ways to write loop statements.

1. for loop:

for (初始化; 条件判断; 循环体执行后的操作) {
   // 循环体
}

1. while loop:

while (条件判断) {
   // 循环体
}

1. do-while loop:

do {
   // 循环体
} while (条件判断);

1. Enhance for loop (for-each loop):

for (元素类型 元素变量 : 遍历对象) {
   // 循环体
}

These looping statements can be used in various ways according to actual needs. For instance, the for loop is suitable for cases with a known number of iterations, while the while loop is ideal for situations with unclear iteration times but definite termination conditions. The do-while loop is appropriate for scenarios where the loop body must be executed at least once, and the enhanced for loop is suitable for traversing array or collection types like sets.
